Homework Help: Two Closed Thermodynamic Cycles Conceptual Question

  1. Dec 4, 2008 #1
    Imagine processing the gas clockwise through Cycle 1 and then counterclockwise through Cycle 1. Compare these two processes on the basis of the heat energy transferred to the gas in the entire cycle.
    Choose the correct comparison symbol.
    Q_clockwise for Cycle 1 <,=,> Q_counterclockwise for Cycle 1.

    So I know that W_clockwise for Cycle 1> W_counterclockwise for Cycle 1. and Delta U = Q - W

    so is it > ?


    Imagine processing the gas clockwise through Cycle 1 and then clockwise through Cycle 2. Compare these two processes on the basis of the heat energy transferred to the gas in the entire cycle.
    Choose the correct comparison symbol.
    Q_clockwise for Cycle 1 <,=,> Q_clockwise for Cycle 2

    I know that W_clockwise for Cycle 1= W_clockwise for Cycle 2

    so Would the answer be Q_clockwise Cycle 1 is equal to Q_clockwise Cycle 2?
