A) \[180\,\,\text{J}\]
B) \[70\,\,\text{J}\]
C) \[110\,\,\text{J}\]
D) \[30\,\,\text{J}\]
Correct Answer: B
Solution :
Heat added to the system\[\Delta Q=110\,\,\text{J}\] Internal energy\[\Delta U=40\,\,\text{J}\] External work done is given by \[\Delta W=\Delta Q-\Delta U=110-40\] \[=70\,\,\text{J}\]You need to login to perform this action.
