Thermodynamics Question 13
Question: During the adiabatic expansion of 2 moles of a gas, the internal energy of the gas is found to decrease by 2 joules, the work done during the process on the gas will be equal to
[CPMT 1988]
Options:
A) $ R(T-T _{1}) $
B) $ \frac{R}{\gamma -1}(T-T _{1}) $
C) RT
D) $ R(T-T _{1})(\gamma -1) $
Show Answer
Answer:
Correct Answer: B
Solution:
$ W _{adi}=\frac{R}{\gamma -1}(T _{i}-T _{f})=\frac{R}{\gamma -1}(T-T _{1}) $
