A) \[{{U}_{A}}={{U}_{D}}\]
B) \[{{U}_{B}}<{{U}_{A}}\]
C) \[{{U}_{B}}={{U}_{C}}\]
D) \[{{U}_{C}}>{{U}_{D}}\]
Correct Answer: B
Solution :
Internal energy of a gas \[U=\frac{3}{2}nRT\] where, R is constant. Thus, for a given number of moles of the same gas \[U\propto T\] From the graphs, we conclude that \[{{U}_{A}}={{U}_{D}}\] \[{{U}_{B}}={{U}_{C}}\] \[{{U}_{B}}>{{U}_{A}}\] \[{{U}_{C}}>{{U}_{D}}\]You need to login to perform this action.
