1.	500 jouleof heat was suppliedto 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 ?
Answer» SOLUTION :At CONSTANT volume, `DeltaV=0`. Applying `DeltaU= Q+w=q+PDeltaV, ` we get `DeltaU = q= 500J`.
