Question

A given mass of a gas expands from a state A to the state B by three paths 1,2 and 3 as shown in T-V indicator diagram. If W subscript 1 end subscript comma text end text W subscript 2 end subscript and W subscript 3 end subscript respectively be the work done by the gas along the three paths, then

  1. W subscript 1 end subscript greater than W subscript 2 end subscript greater than W subscript 3 end subscript    
  2. W subscript 1 end subscript less than W subscript 2 end subscript less than W subscript 3 end subscript    
  3. W subscript 1 end subscript equals W subscript 2 end subscript equals W subscript 3 end subscript    
  4. W subscript 1 end subscript less than W subscript 2 end subscript comma text end text W subscript 1 end subscript greater than W subscript 3 end subscript    

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