Question

A sample of ideal monoatomic gas is taken round the cycle ABCA as shown in the figure. The work done during the cycle is

  1. 3pV    
  2. Zero    
  3. 9pv    
  4. 6pv    

The correct answer is: 3pV


    The work done=area of p-V graph
    =area of triangle ABC
    equals fraction numerator 1 over denominator 2 end fraction cross times 3 p cross times 2 V equals 3 p V
