During the adiabatic expansion of 2 moles of a gas, the change in internal energy was found to be equal to -100 J. The work done during the process will be equal to
A) zero
B) -100 J
C) 200 J
D) 100 J
Correct Answer:
D
Solution :
For adiabatic expansion \[dQ=0\] So, by \[dQ=dU+dW\] \[dW=-dU\] \[=100J\]
