In changing the state of thermodynamics ...

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

From 2nd law of thermodynamics `= U + W rArr U = Q - W`.
