A) \[\Delta Q=\Delta U+\Delta W\]
B) \[\Delta Q=\Delta U-\Delta W\]
C) \[\Delta Q=\Delta W-\Delta U\]
D) \[\Delta Q=-\Delta W-\Delta U\]
Correct Answer: B
Solution :
[b] From FLOT\[\Delta Q=\Delta U+\Delta W\] |
Q Heat supplied to the system so DQ ® Positive |
and work is done on the system so DW ® Negative |
Hence +DQ = DU DW |
