When you add heat, the molecules move faster!

Along Path a:
$ W = 2p_0(2V_0 - V_0) = 2p_0 V_0$
$ W = 2p_0(2V_0 - V_0) = 2p_0 V_0$

Along Path b:
$ W = p_0(2V_0 - V_0) = p_0 V_0$
$ W = p_0(2V_0 - V_0) = p_0 V_0$

Cool Stuff


http://www.personalityquiz.net/profiles/refrigerator.htm This is the legendary refrigerator quiz. "According to Andersen consulting worldwide, around 90% of the professionals they tested got all of the questions wrong. But many pre-school children got several correct answers." What does this mean? Take it and find out!

http://home.howstuffworks.com/refrigerator3.htm Explains about refrigeration. Starts of with " Imagine some creature that is able to live happily in an oven at 400 degrees Fahrenheit....". Also fun fact about butane lighters which you will have to go see for yourself

http://science.howstuffworks.com/big-bang-theory7.htm The Big Bang violates the first law of thermodynamics. Enough said.


http://www.youtube.com/watch?v=s2EMXle8raw&feature=related Has very little to do with thermodynamics but an amazing physics trick.

http://www.youtube.com/watch?v=s7waCsbywzM Shows an experiment that proves that as temperature goes up, molecules travel faster.

http://www.mrcoulter.com/LECTURES/21thermo_Ideal_G.pdf -- Outlines the entire chapter in a very easy, understandable way. It includes equations, applications, and step-by-step instructions.

http://hyperphysics.phy-astr.gsu.edu/HBASE/kinetic/idegas.html - Again, just another brief chapter outline according to a physics website.

http://www.youtube.com/watch?v=AM_GAbvacbE - A very down to earth, real life application of gas laws. An experiment relating pressure, volume, and temperature.







Natland Note (3/9/10): There needs to be more added here. Nate is the only person who has put up a significant amount. Rony, you have put up a few sites, but I am looking for my useful sites that have good physics. Too many of the link are either purely a joke or are amateur physics.
