In the reported figure, there is a cyclic process ABCDA on a sample of 1 mol of a diatomic gas. The temperature of the gas during the process AB and CD are T1 and T2 T1>T2 respectively.

Choose the correct option out of the following for work done if processes BC and DA are adiabatic.

  1. WAB=WDC
  2. WAD=WBC
  3. WBC+WDA>0
  4. WAB<WCD

Solution

Work done in adiabatic process =-nRγ-1 Tf-Ti

 WAD=-nRγ-1 T2-T1

and WBC=-nRγ-1 T2-T1

 WAD=WBC
