What will be the change in internal energy when 12 kJ of work is done on the system and 2 kJ of heat is given by the system?

A

`+10kJ`

B

`-10kJ`

C

`+5kJ`

D

`-5kJ`

Text Solution

Verified by Experts

The correct Answer is:
A
Heat evolved = -2 kJ
Work done on the system `=+12kJ`
`DeltaU=q+w=-2+12=+10k`
