OK - that might be what I was missing. (And I was glad to hear I'm not the only one confused about this.) I can see I still need to think about this and also play with some problems.

What am I missing? According to the ideal gas law, as volume increases, temperature increases. However I’m not sure I understand why. I certainly understand the motion of the molecules equals the kinetic energy of the molecules. The faster the molecules bounce about, the more thermal energy the...
