In a process, `701 J` of heat is absorbed by a system and `394 J` of work is done by the system. What is the change in internal energy for the process?

A

`-464J`

B

`+464J`

C

`+307J`

D

`-307J`

Text Solution

Verified by Experts

The correct Answer is:
C
We know, internal energy change, `DeltaE=q+W`
`=+701J+(-394J)=+307J`.
Hence, internal energy of the system increases by 307 J.
