KillGorack / Physics 2010 / An ideal gas at pressure, volume, and temperature, P0, V0, and T0, respectively, is heated to point A, allowed to expand to point B also at A's temperature 2T0, and then returned to the original condition. The internal energy decreases by 3P0V0/2 going from point B to point T0. How much heat left the gas from point B to point T0? 1) 0 2) P0V0/2 3) 3P0V0/2 4) 5P0V0/2 5) 3 P0V0

The following physics responses are provided by a student and, as such, should be considered in that context. While every effort is made for accuracy, absolute correctness cannot be fully guaranteed.

Question An ideal gas at pressure, volume, and temperature, P0, V0, and T0, respectively, is heated to point A, allowed to expand to point B also at A's temperature 2T0, and then returned to the original condition. The internal energy decreases by 3P0V0/2 going from point B to point T0. How much heat left the gas from point B to point T0? 1) 0 2) P0V0/2 3) 3P0V0/2 4) 5P0V0/2 5) 3 P0V0
Answer 5P0V0/25P0V0/2
