On the last test, one of the questions was discussing whether or not heat was being transferred when a balloon filled with gas was expanded to a larger volume and lower pressure while maintaining the same temperature. I thought that it was not because the temperature was not changing, however the answer is yes, so I was just wondering why that is. Thanks!
Heat is being transferred because pressure and volume are changing. Even though the temperature is constant, that is because the changing temperature evens out and becomes non changing even though its gaining some and losing some from the pressure and volume change.
