In changing the state of thermodynamics from A to B state, the heat required is Q and the work done by the system is W. The change in its internal energy is

A

Q+W

B

Q-W

C

Q

D

`(Q-W)/2`

Text Solution

Verified by Experts

The correct Answer is:
B
`DeltaQ = DeltaU + DeltaW`
`rArr DeltaU = DeltaQ - DeltaW =Q -W` (using proper sign)
