A) it does 250 J of work and its temperature rises
B) it does 250 J of work and its temperature falls
C) it does 550 J of work and its temperature rises
D) it does 550 J of work and its temperature falls
E) 250 J of work is done on the system
Correct Answer: B
Solution :
From first law of thermodynamics \[\Delta U=Q-W,\]we have Given, \[\Delta U=-400\,J,Q=-150J\] \[\therefore \] \[W=400-150=+250J,\] temperature rises.You need to login to perform this action.
