Homework Help: Ideal Gas

  1. Aug 7, 2005 #1
    An ideal gas at pressure, volume, and temp, Po, Vo, and To, respectively, is heated to point A, allowed to expand to point B also at A's temperature 2To, and then returned to the original condition. The internal energy increases by 3PoVo/2 going from point B to point To. How much heat left the gas from point B to point To?

    a. 0 b. PoVo/2 c. 3PoVo/2 d. 5PoVo/2


    Not sure about this one. Any suggestions? Thanks

    Can't understand how internal energy increases if the temp. changes from 2T0 to T0??
