Question

In the figure given two processes A and B are shown by which a thermo-dynamical system goes from initial to final state F. If capital delta Q subscript A end subscript and capital delta Q subscript B end subscript are respectively the heats supplied to the systems then

  1. capital delta Q subscript A end subscript equals capital delta Q subscript B end subscript    
  2. capital delta Q subscript A end subscript greater or equal than capital delta Q subscript B end subscript    
  3. capital delta Q subscript A end subscript less than capital delta Q subscript B end subscript    
  4. capital delta Q subscript A end subscript greater than capital delta Q subscript B end subscript    

The correct answer is: capital delta Q subscript A end subscript greater than capital delta Q subscript B end subscript


    capital delta Q equals capital delta U plus capital delta W semicolon DU does not depend upon path.
    because capital delta W subscript A end subscript greater than capital delta W subscript B end subscript Þ capital delta Q subscript A end subscript greater than capital delta Q subscript B end subscript
