Question

In the cyclic process shown in the figure, the work done by the gas in one cycle is

  1. 28 P subscript 1 end subscript V subscript 1 end subscript    
  2. 14 P subscript 1 end subscript V subscript 1 end subscript    
  3. 18 P subscript 1 end subscript V subscript 1 end subscript    
  4. 9 P subscript 1 end subscript V subscript 1 end subscript    

The correct answer is: 9 P subscript 1 end subscript V subscript 1 end subscript


    Work done = Area under curve equals fraction numerator 6 P subscript 1 end subscript cross times 3 V subscript 1 end subscript over denominator 2 end fraction= 9 P1V1
