Question

A thermodynamic system undergoes cyclic process ABCDA as shown in figure. The work done by the system is

  1. P subscript 0 end subscript V subscript 0 end subscript    
  2. 2 P subscript 0 end subscript V subscript 0 end subscript    
  3. fraction numerator P subscript 0 end subscript V subscript 0 end subscript over denominator 2 end fraction    
  4. Zero    

The correct answer is: Zero


    WBCOB = – Area of triangle BCO equals negative fraction numerator P subscript 0 end subscript V subscript 0 end subscript over denominator 2 end fraction
    WAODA = + Area of triangle AOD equals plus fraction numerator P subscript 0 end subscript V subscript 0 end subscript over denominator 2 end fraction
