Question

P-V diagram of an ideal gas is as shown in figure. Work done by the gas in process ABCD is

  1. 4 P subscript 0 end subscript V subscript 0 end subscript    
  2. 2 P subscript 0 end subscript V subscript 0 end subscript    
  3. 3 P subscript 0 end subscript V subscript 0 end subscript    
  4. P subscript 0 end subscript V subscript 0 end subscript    

The correct answer is: 3 P subscript 0 end subscript V subscript 0 end subscript


    W subscript A B end subscript equals negative P subscript 0 end subscript V subscript 0 end subscript, W subscript B C end subscript equals 0 and W subscript C D end subscript equals 4 P subscript 0 end subscript V subscript 0 end subscript
    Þ W subscript A B C D end subscript equals negative P subscript 0 end subscript V subscript 0 end subscript plus 0 plus 4 P subscript 0 end subscript V subscript 0 end subscript equals 3 P subscript 0 end subscript V subscript 0 end subscript
