A) \[\Delta Q=\Delta U+\Delta W\]
B) \[\Delta Q=\Delta U-\Delta W\]
C) \[\Delta Q=\Delta W-\Delta U\]
D) \[\Delta Q=-\Delta W-\Delta U\] where \[\Delta U\] is the internal energy
Correct Answer: B
Solution :
From FLOT \[\Delta Q=\Delta U+\Delta W\] \[\therefore \] Heat supplied to the system so \[\Delta Q\to Positive\] and work is done on the system so \[\Delta W\to Negative\] Hence \[+\Delta Q=\Delta U-\Delta W\]You need to login to perform this action.
