An ideal gas is taken through the cycle A 
B 
C 
A, as shown in the figure. If the net heat supplied to the gas in the cycle is 5 J, the work done by the gas in the process C 
A is
Text Solution
Verified by ExpertsThe correct answer is:
A
(as V = constant)
From first law of thermodynamics,
Q = 
W + 
U
U = 0
Process ABCA is cyclic,
Q = 
W AB + 
W BC + 
W CA
W CA = 
Q - 
W AB - 
WBC
= 5-10-0 = -5J
