A) PV
B) \[\frac{\text{R}}{\text{ }\!\!\gamma\!\!\text{ -1}}\]
C) \[\frac{PV}{\gamma -1}\]
D) \[\frac{\text{ }\!\!\gamma\!\!\text{ PV}}{\text{ }\!\!\gamma\!\!\text{ -1}}\]
Correct Answer: C
Solution :
The change in internal energy at constant pressure is \[dV=\frac{1}{\gamma -1}({{P}_{2}}{{V}_{2}}-{{P}_{1}}{{V}_{1}})\] \[=\frac{1}{\gamma -1}[P\times 2V-P\times V]\] \[=\frac{PV}{\gamma -1}\]You need to login to perform this action.
