Transferring of Heat
In the situation that "A ballon filled with gas expands to a larger volume and lower pressure while maintaining the same temperature," how is heat considered to be transferred in the process?

The balloon expands because the kinetic energy increases due to the warmer temperature, making the molecules move faster and hit the inside of the balloon harder and more frequently.

Re: Transferring of Heat
How is this caused by a warmer temperature because it says that it maintains the same temperature

In this situation, I believe that the balloon filled with gas is expanding and thus the gas is doing work on the balloon (causing the expansion), but at the same time heat is given off by the balloon, and this is what is maintaining the same temperature. Remember when temperature is kept constant, we can say that delta(U)=0, and since delta(U)= w+q, it follows that w=-q. -q being the heat given off by the balloon, and +w being the work done on the balloon.
