Question

For one complete cycle of a thermodynamic process on a gas as shown in the P-V diagram, Which of following is correct

  1. capital delta E subscript i n t end subscript    
  2. capital delta E subscript i n t end subscript    
  3. capital delta E subscript i n t end subscript    
  4. capital delta E subscript i n t end subscript    

The correct answer is: capital delta E subscript i n t end subscript


    capital delta E subscript text int end text end subscript equals 0, for a complete cycle and for given cycle work done is negative, so from first law of thermodynamics Q will be negative i.e. Q less than 0.
