An ideal gas is subjected to cyclic process ABCD as depicted in the p-V diagram given below: Which of the following curves represents the equivalent cyclic process?                                        

A)  A                                           

B)  

C)  C                                           

D)  D

Correct Answer: A

Solution :

  During process AB, pressure remains constant, during process BC, pressure is decreasing as well as V is increased. During process CD, volume remains constant. During process DA, volume is decreased as well as pressure is increased. Hence, figure A is equivalent corresponding to the given figure.
