When heat energy of 1500 J is supplied to a gas it is compressed from 10 `m^(3)` to 5 `m^(3)` at a pressure of 100 Pa. the change in internal energy is

A

2000 J

B

1000 J

C

500 J

D

2500 J

Text Solution

Verified by Experts

The correct Answer is:
A
`PDeltaV=P(V_(2)-V_(1))`
`=100(5-10)`
=-500J
`DeltaU=DeltaQ-DeltaW`
=1500-(-500)
=2000J.
