Thermodynamics - Result Question 16

17. A thermodynamic system undergoes cyclic process ABCDA as shown in fig. The work done by the system in the cycle is :

[2014]

(a) P0V0

(b) 2P0V0

(c) P0V02

(d) Zero

Show Answer

Answer:

Correct Answer: 17. (d)

Solution:

  1. (d) Work done by the system in the cycle = Area under PV curve and V-axis

=12(2P0P0)(2V0V0)+

[(12)(3P02P0)(2V0V0)] =P0V02P0V02=0
