How are pressure and heat related and dependent on one another? Give me some "for example"s.
Be reasonably thorough in your explanation, which should be at least a couple of GOOD sentences long.
(BTW i think that sentences like this 1 r beneath u and that u should take the time to present ur best work. in other words show better punctuation capitalization and care in the work u produce and ur written communications. just like we established at the beginning of the year i will start taking off points for poor sentences on ur blog work as well as ur quiz responses. better find that "shift" key! if ur still reading good for u b/c to get full credit on this assignment u need to include a smiley face (a colon & parentheses r fine) in ur blog response. ☺
Pressure is dependent on heat because as the heat of water (or anything) increases, its volume and vapor pressure (the pressure of the evaporated portion of liquid/ solid in a closed container) increase, which increases the total pressure. For example: I once heated a kettle with water in it, but the spout cover was broken, so i duck taped a piece of metal over it. As the water heated, it expanded and steam was created. There was such a large build up of pressure that the kettle failed and burst open. Heat is dependent on pressure because as a liquid becomes more pressurized, it boils slower (because the pressure pushes down on the evaporating molecules, preventing them from escaping in bubbles) which means that the liquid has nowhere to put its extra energy, so it superheats. An example: I can't think of one other than the boiler rocket in the episode. YAY! :)
ReplyDeleteThe total pressure of the water vapor (water that has evaporated due to high temperatures) becomes too high for the inside of the container to contain. Therefore, the water heater explodes and the heater goes flying. As he said the heater was a 30 gallon water heater, but exerted 30,000 gallons of vapor after explosion. Expansion happens inside the heater at great speeds. Example: Popcorn, when you pop the popcorn on the stove, if there is too much heat and pressure exerted inside the foil, the popcorn will pop out of the foil and the pressure from inside will cause a burst in the foil.
ReplyDeleteAs seen in the video, pressure and heat are directly proportional. As heat rises, pressure rises, and as pressure lowers, heat lowers, and vice-versa. For example, race car tires are not filled with as much air as normal tires on regular cars because the race car tires heat up more, causing the pressure to increase inside the tires, which makes them more vulnerable to being damaged, because they will have less contact with the road with higher pressure. :)
ReplyDeleteThe myth-busters proved that heat and pressure are dependent on one another through their experiment with the water heater. When you raise the temperature of something, the molecules become more condensed and close together; thus, there is more pressure within the substance. As the heat rose in the water heater, the pressure also increased. For example, if you increase the heat of a rice cooker, the pressure within will also increase and create more steam. :)
ReplyDeleteHeat and pressure are related in that when one increases, the other one increases too. We could see that one is dependent on the other, thus enforcing the principles of direct proportion. When pressure rises, heat rises, and vice-versa - this led to the outcome of the final pressurized tank in the video. The heat was high enough to considerably bump up the pressure level (the first two experiments in the video didn't have enough heat and pressure to make it fully sky-rocket into the atmosphere.
ReplyDeleteFor example, if you drill a hole in the some sort hard surface such as the ground or metal, the friction and pressure would cause the drillbit to become warm to the touch.

ReplyDeleteHeat and pressure work with one another, meaning that if one increases the other one will increase, and vice versa. In Myth-Busters, they proved that they are dependent on each other when they tried to make the water heater into a rocket using heat and pressure. Another example of how heat and pressure are related is when one boils water and puts a lid over the pot, the pressure and heat increase, and the water will rise. :)
ReplyDeleteHeat is measured by how rapidly molecules vibrate; therefore, heat describes how far apart vibrating molecules in an object are. The hotter something gets, the more it will expand and conversely, the greater something expands the denser it becomes. Finally, if something dense is contained within another object, then its internal pressure will increase. Thus, heat, by causing objects to expand, increases pressure as objects heat up and expand :)
ReplyDeleteThe Mythbusters episode proved that heat and pressure are related. When heat increases, the pressure increases, and when heat decreases, the pressure decreases. This concept was displayed in the episode when they attempted to make a rocket out of a water heater. With more heat, the particles get closer together and condense, so therefore, there is more pressure. Like we talked about in class, heat is caused by the movement or vibrations of molecules, and as they move more and cause more heat, they vibrate faster and closer, creating more pressure. For example, while cooking food on a stove, as you turn the temperature up on the stove, the particles vibrate and move closer, so there is more pressure as more heat is created; the increasing pressure causes it to feel even hotter, so if you even put your hand over the stove, you feel the burning heat. The increasing pressure helps cook the steak, for example, and causes it to heat up and the air above it as well. :)
ReplyDeleteHeat is dependent on pressure because the pressure causes a slowing in terms of boiling speed causing overheating as molecules have no where to go. An example of this is water boiling in an enclosed pot that as a result heats up. Pressure is dependent upon heat because as heat rises/increases so does the level of pressure (same goes for decreasing levels of pressure being directly proportional to a decrease in heat). An example of this is a house on fire (sorry for the grimness) where the air pressure is increased. :)
ReplyDeleteHeat and pressure have a directly proportional relationship, as when the heat starts to rise, the pressure does too. This is because heat makes molecules vibrate faster depending on the temperature, and when molecules vibrate, they get farther apart. When these molecules spread out over a greater distance, it increases the the volume of the substance, therefore increasing the pressure. An example of heat making things expand is when it interacts with water. When water gets to a certain temperature, it evaporates. This is the result of heat causing water to expand to a gas.
ReplyDeleteJaimie and Adam clearly show how heat is directly proportional to pressure. An increase in heat, results in an increase in pressure. By increasing the temperature inside the water heater, the speed of the molecules is also increased which increases the force of the molecules hitting the container. For example, a pressure cooker cooks much faster that a normal pan because the heat and the pressure are much greater. :)
ReplyDeleteHeat and pressure are related in the sense that when heat rises, pressure rises. They are directly proportional to each other. In the Mythbusters episode, they raised the temperature in the the water heater until it had so much pressure that the water forced its way out of the bottom, sending the appliance upwards like a rocket.
ReplyDeleteA real-world example: In a volcano as the magma works its way up to the crust, it heats up the ground directly below the surface until the pressure becomes so great, that it erupts. :)
Heat and pressure are directly proportional to each other, which means that when one increases the other one will as well. In the episode of Myth Busters that we watched today, they proved that they are directly proportional to each other when during their experiment to get the water heater to explose. Another example of how heat and pressure are related is when you rub your hands together causing pressure though friction, your hands begin to feel warm thus increasing in temperature as the pressure increases. :)
ReplyDeletePressure and heat are directly linked because heat tends to expand objects which in turn increases the pressure. For example extremely hot water expands which is what caused the water heater to eventually explode as a result of the expanding pressure due to the waters increased temperature. Also the pressure of a person's leg in jeans increases when the person's leg increases in temperature because the leg begins to expand in the jeans. Heat and pressure are related and directly proportional in the sense that increased heat means increased pressure. :)
ReplyDeletePressure is dependent on water and the heat of the water because as the heat increases the more vapor/steam comes off of the water creating more pressure in the container that the heated water is in. For example, whenever I cook certain foods, to boil the water i put a lid over the pot but once the water is boiling and there is a lot of steam the lid starts to move around a lot as if it was going to come over. That shows the pressure of steam building up between/inside the pot and cover. The same sort of build up happened in the heater. As the pressure and heat of the water increased, more steam was created and once the gas could not compress any longer the heater exploded.
ReplyDelete:)
The higher the temperature is, the higher pressure the pressure is and vise-versa (the lower the temperature is the lower the pressure). One example of this was present in the episode of Myth Busters we watched. In order to get the water heater to explode, they had to raise the temperature which resulted in more pressure. Another example is dribbling a basketball in warm weather versus dribbling a basketball in cold weather. Dribbling the ball in warm weather is easier because of the pressure of the molecules inside the ball. However, it is harder to dribble the ball in cold weather because the pressure is significantly lower resulting in the ball bouncing less. :)

ReplyDeleteWater and pressure are directly porportional, as the heat level increases the pressure level does as well. In the episode we witnessed, we saw just as the temperature of the water rose,so did the pressure, eventually causing the water heater to explode up high into the air, performing a rocket type experience. For example, when you are inside a steaming hot suana, that in enclosed you may feel pressure against your skin and when you walk out you would feel normally. Therefore this is an example of how heat, affects pressure and they are both directly porportional to eachother. :)
ReplyDeletePressure and heat are dependent upon each other in a directly proportional way. When the heat was turned up inside the water heater, so was the pressure. This is because the heat causes the molecules to vibrate faster and therefore they take up more room. For example, in a bottle of soda, the gas is trapped in the soda in liquid form but when the bottle is shaken the molecules go back to their gaseous state and take up more room causing the bottle to explode and the foam to spill out. Similarly to the liquid gas, the steam was perfectly fine in the heater until too much of it turned to gas and needed more volume with the same amount of mass. If that volume isn't accessible then the pressure increases and can create an explosion. ☺
ReplyDeletePressure and heat have a directly proportional relationship because higher heat causes molecules to move much faster. This raises the pressure inside whatever container the molecules are in because the molecules bounce of each other and push against the walls of the container much more than at a lower heat. This can be seen in a pressure cooker, a cooking device that has a lid which contains heat, vapor, and steam below a certain pressure, allowing foods to be heated up much more quickly since pressure and heat complement each other. :)

Pressure and Heat seem to be directly proportional. As Pressure increases, so does the temperature. When the heat was increased in the water heater experiment, the pressure went up as well. Additionally, an increase in temperature causes water to expand into its gaseous state and therefore push out on the outer walls of the heater because there is no room for the vapor.. Eventually, the pressure increased to such a high amount that even the water heater could not hold the pressure. As the pressure decreases after exploding, so does the temperature. Therefore, pressure and heat are directly proportional. :) :) :) :) HA!
ReplyDeleteAdam and Jamie prove in their water heater experiment that pressure and heat are directly proportional. As the temperature increased, the pressure also increased. The heat was able to create enough pressure for the water heater to explode! Another example is when you rub your hands together, the friction between the two surfaces causes your hands to heat up - revealing that the there was a rise in temperature and pressure! :)
ReplyDeleteThe Mythbuster's crew prove that pressure and heat are directly proportional by teaching us that when the pressure was increased so did the heat. The increased pressure within the confinded space causes the molecules to collide with each other and speed up, increasing the temperature. In the Mythbuster's experiment the pressure in the water heater got so high that it was no longer able to be contained by the constraints of the heater.Another example of pressure and temperature is when playing tennis on a cold morning the temperature causes the pressure in the ball not to be at its highest point, causing the ball to bounce slightly less. =)
ReplyDeleteThe Mythbusters proved that pressure and heat are directly effective of each other because when the water pressurized in the hot water holder, it made the holder expand and as a result blow up releasing the pressure but at the same time the built up water over such a grossing hot temperature released pure steam that shows the direct proportionality. Nevertheless, the holder blowing up at the end is the clearest result of why the expansion of heat and pressure build up are proportional to each other.
ReplyDeleteHeat is directly proportional to pressure: When something gets hot the pressure increases. For example: When you fill a water bottle with hot or cold water it expands or contracts respectively. XD
ReplyDeleteHeat is directly proportional to Pressure.As Heat increases the pressure increases because the molecules inside of a space begin to move faster and bounce off each other quicker. As this happens the pressure within the space increases. For examplem, when you microwave a marshamllow for too long the pressure inside increases and the marhsmallow expands until it explodes. :)
ReplyDeletePressure is dependent and directly proportional to heat. Therefore, as heat rises, so does pressure, and vice versa. In the rocket experiment, heat in the water heater increased, so did the pressure because the hotter heat molecules began to bounce off each other at a much greater rate, thus increasing the pressure. An example of this interaction between heat and pressure is when you are cooking food like rice. As the rice continually gets hotter and then you life the top of the rice cooker, there will be a lot more steam and water vapor because of the extremely high heat and pressure. :)

ReplyDeletePressure and heat are directly proportional. When pressure rises so does heat. Pressure and Heat also directly effect each other. When The water began to boil pressure in the water heater rose. An example of heat and pressure is when you boil water if you put it inside a water bottle the water bottle will expand proportionally due to the heat. Another example is a Hot water bottle, you can put hot enough water to the point where the bottle will explode. :-)
ReplyDeleteThe water heater experiments proves that heat and pressure are related. The water heater exploded because the pressure became too high. As the water heated up, it became water vapor and expanded, so the pressure increased. The water heater eventually wasn't able to contain the increase in pressure. A rise in temperature causes a rise in pressure. :)
ReplyDeleteWell first of all, heat is created because molecules vibrate together very rapidly and increase their surface area by doing so. However you may question "Well if they increase their surface area.. shouldnt hot air (for example) be LESS dense and therefore have less pressure?" Not particularly. For example, if you take an average kettle (that makes delicious tea,) fill it with boiling water, and place a plug into the mouth of the kettle, the kettle will eventually make a high pitched noise. The hot air and water is compacted in a smaller area and an increased volume and therefore has greater pressure. This demonstrates that pressure is completely dependent upon the volume/area of heat. :)
ReplyDeleteHeat is directly proportional to pressure. As something starts to rise in temperature, the pressure starts to increase too. With greater heat, the molecules inside started to bounce off each other at a much faster rate which increases the pressure between them. An example is the water heater, with the increase of temperature, the pressure built up so greatly that it couldn't handle all of the pressure and it flew in the air. :)
ReplyDeleteSince heat and pressure have a proportional relationship, as heat increases so will pressure. Since everything has a set capacity for how much pressure it can handle, at some point the container will not be able to contain the pressure any more. For example, there was only so much pressure the water heater could handle. To test the water heater rocket, the MythBusters had to increase the heat which would then increase the pressure (directly proportional/dependent on each other) and eventually the heater was not able to contain all that pressure. :)
ReplyDeleteBasically heat is directly proportional to pressure, so when the heat increases then the pressure also increases. In the MythBusters video, the water heater had a limited capacity for the pressure that it could handle; so when the heat was increased, the pressure inside the tank also increased and made it go "BVROOOOOOM". An example of this would be if I heat up a soda can. The pressure inside of the soda can would build up due to the heat that is being applied. Eventually the extra pressure will have to go somewhere and the can would explode. :p
ReplyDeleteHeat and pressure are directly proportional. As the temperature goes up, the pressure goes up, especially in a closed space. When molecules become hotter, they start moving faster and faster, like that improv that we did in class, and the faster those molecules move the more they bounce off each other creating more pressure. For example, when I am cooking pasta I always put a lid on top of the pot. Once the lid is on the steam created by heat causes more pressure.
ReplyDeleteThere was a particular amount of pressure that could be held and as both the pressure and the heat grew there was no more room causing it to explode upwards. When the pressure increases, so does the heat (which means they are directly proportional).
ReplyDeleteExample: When cooking food in a pot the heat and pressure rise quicker(:
The water heater in the Mythbusters episode exploded because heat and pressure are directly proportional to one another; when the water heater became hotter the air molecules began to speed up and hit one another faster causing the pressure to increase, which eventually led to the explosion. Another example of heat and pressure being related to each other is a car engine because as the motor spins faster it creates friction that creates heat and leads to an increase in pressure. But, car engines have a cooling system to prevent themselves from exploding. :D
ReplyDeletePressure and heat are very related in many different ways. First, have a directly proportional relationship. For example if the pressure in the water heater is very high, the heat will also be very high as well. If one of the two have a certain reaction, the other one will react with it and have a similar reaction; however, the water heater can only withstand a certain amount of pressure which is what had caused it to overheat and explode in the video from mythbusters. Another example is when water gets to very high temperatures it will begin to evaporate and turn into a gas because of the excessive heat and it could create steam as well. ;)

Pressure and heat are directly proportional, in other words, when one increases, the other does the same. In fact, the molecules in a hot substance have more energy;thus, they vibrate and move around quickly, causing the substance to expand. As the substance expands, its pressure increases. Mythbuster's effectively proved this theory. For example, they increased the temperature inside a pressurized water heater and eventually it exploded. This is due to the molecules expanding as they gain more energy through heat, causing the pressure to drastically increase. The pressure was so great that the water heater exploded. This effect can happen to anything. For example, if you heat up a soda can, the molecules in the can will gain more energy and expand, causing an increase in pressure. Eventually the can will break open. Evidently demonstrated by the Mythbuster's experiment, heat and pressure are dependent on each other. :)
ReplyDeleteTemperature and pressure are directly proportional. If one increases the other does too. Temperature can be heat. If you increase the heat of any liquid, the molecules in that liquid will increase the space around it because their speed increased. When the molecules use more space the pressure increases. A good example is the water heater. Mythbusters proves that when the temperature of water is increased- heated- the pressure increases and has the ability to cause a deadly rocket.

Pressure is directly proportional to temperature, so as the temperature increases so does the pressure. Heat builds up in the heater until the molecules are moving so fast that they can't be contained in the heater causing it to explode... the explosion is also so big because of how fast the heat molecules are moving and spreading out.
