Question

An ideal monoatomic gas is taken round the cycle ABCDA as shown in following P-V diagram. The work done during the cycle is

  1. PV    
  2. 2 PV    
  3. 4 PV    
  4. Zero    

The correct answer is: 4 PV


    Work done = Area of curve enclosed
    equals 2 V cross times 2 P equals 4 P V
