Thermodynamics Help

  1. Jun 11, 2007 #1
    1. The problem statement, all variables and given/known data

    In the operation of of a refrigerator there is a heat flow out of the reservoir at a lower temperature and a heat flow into a 2nd reservoir at a higher temperature.Explain why this process does not violate the Clausius statement of 2nd law.

    2. Relevant equations
    3. The attempt at a solution

    My attempts:Please check and confirm if I am correct

    Because WORK is being done by the refrigerator compressor to
    accomplish this transfer from Tcold to Thot. The Clausius statement
    only prohibits heat flow from Tcold to Thot when NO WORK is being
    done to enable the transfer.

    Yes. The work is provided by the motor in the compressor.
