200 joules of heat was supplied to a system at constant volume. It resulted in the increase in temperature of the system from 298 to 323 K. What is the change in internal energy of the system ?

A

400 J

B

200 J

C

50 J

D

150 J

Text Solution

Verified by Experts

The correct Answer is:
B
At constant volume, `DeltaV=0`
`w=-PDeltaV=0" "DeltaU=q=200J`
