Heat and internal energy of gas

  1. Nov 19, 2007 #1
    One mole of an ideal diatomic gas at room temperature undergoes a transition from a to c along the diagonal path in Figure 19-23.
    [​IMG]
    (a) During the transition, what is the change in internal energy of the gas?
    -4987 J
    (b) How much energy is added to the gas as heat?
    ____ J
    (c) How much heat is required if the gas goes from a to c along the indirect path abc?
    5013 J

    I got part a and c right. I found the energies for path abc and added them together, because I couldnt find a way with path ac. Does the path I took matter for the heat? How do I find it using path ac?
