Question

An ideal gas is taken around ABCA as shown in the above P-V diagram. The work done during a cycle is

  1. Zero    
  2. fraction numerator 1 over denominator 2 end fraction P V    
  3. 2 PV    
  4. PV    

The correct answer is: PV


    Work done = Area enclosed by the curve
    equals fraction numerator 1 over denominator 2 end fraction left parenthesis 3 V minus V right parenthesis left parenthesis 2 P minus P right parenthesis equals P V
