A) \[\Delta {{U}_{a}}=\Delta {{U}_{b}}\]
B) \[\Delta {{U}_{a}}>\Delta {{U}_{b}}\]
C) \[\Delta {{U}_{a}}<\Delta {{U}_{b}}\]
D) \[\Delta {{U}_{a}}=\Delta {{U}_{b}}=0\]
Correct Answer: B
Solution :
(i) Volume is constant \[i.\,e.,\] \[\Delta V=0\] \[\Delta U=Q-p\Delta V\] \[\Delta {{U}_{a}}=Q\] (ii) Pressure is constant, i.e. \[\Delta {{U}_{b}}=Q-p\Delta V\] \[\therefore \] \[\Delta {{U}_{a}}>\Delta {{U}_{b}}\]You need to login to perform this action.
