Question

Starting with the same initial Conditions, an ideal gas expands from Volume V subscript 1 end subscript to V subscript 2 end subscript in three different ways. The Work done by the gas is W subscript 1 end subscript if the process is purely isothermal, W subscript 2 end subscript if purely isobasic and W subscript 3 end subscript if purely adiabatic Then

  1. W subscript 2 end subscript greater than W subscript 1 end subscript greater than W subscript 3 end subscript    
  2. W subscript 2 end subscript greater than W subscript 3 end subscript greater than W subscript 1 end subscript    
  3. W subscript 1 end subscript greater than W subscript 2 end subscript greater than W subscript 3 end subscript    
  4. W subscript 1 end subscript greater than W subscript 3 end subscript greater than W subscript 2 end subscript    

The correct answer is: W subscript 2 end subscript greater than W subscript 1 end subscript greater than W subscript 3 end subscript
