500 joule of heat was supplied to a system at constant volume. It resulted in the increase of temperature of the system from `20^(@)C` to `25^(@)C`. What is the change in internal energy of the system ?

Text Solution

Verified by Experts

The correct Answer is:
`DeltaU = 500 J`
At constant volume, `DeltaV=0`. Applying `DeltaU= q+w=q+PDeltaV, ` we get `DeltaU = q= 500J`.
