In changing the state of thermodynamics from

A

B

state, the heat required is

Q

and the work done by the system is W . The change in its internal energy is

View answer and explanation

Correct option: B

Q - W

Option B (

Q - W

) is correct because, according to the first law of thermodynamics, the change in internal energy is the heat added to the system minus the work done by the system.
