A system absorbs `600J` of heat and work equivalent to `300J` on its surroundings. The change in internal energy is:

A

`300J`

B

`400J`

C

`500J`

D

`600J`

Text Solution

Verified by Experts

The correct Answer is:
D
We know that `DeltaE=Q+W=600+(-300)=300J`
`W=-300` , because the work is done by the system.
