Homework Help: PV Diagram

  1. Aug 16, 2011 #1
    Can some one check my work, I'm not sure if I am understanding how internal energy heat and work are related.

    Work is defined to be positive if the system does work on the environment.

    Q=[itex]\Delta U[/itex] +W

    I am showing if the process is positive, negative or 0.

    Also this is suppose to be an ideal gas
