I Hate to Sound Dense, but...

As with light, so with sound. Well, not always, but there are a few parallels, and one of those parallels is speed. The material (or medium) that sound passes through affects its speed. How so?

For a benchmark, let's use the speed of sound in air at the beach in Malibu on sunny, 70-degree day -- 1,125 feet/sec (666 mph), also known as Mach 1.

How will the speed of a given sound change (FASTER, SLOWER, NO CHANGE) in the following scenarios:

...on top of Mount Everest?

...submerged in a pool?

...through a wall?

...in Florida (same air temperature as Malibu, at sea leavel, but much more humid)?

...in space?

Excluding space, pick the option above that you think will transmit sound waves fastest, and explain WHY.

It Takes Two to Tango -- Temperature and Pressure!

Having watched the Mythbusters, Adam & Jaimie, release the full force of a PRESSURIZED WATER HEATER on a runway overlooking San Francisco, there clearly exists a link between heat and pressure. But what is it?....That's my question to you.

How are pressure, heat, and volume 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 & parenthesis r fine) in ur blog response. ☺
