`DeltaU=q-pDeltaV.` If the process is carried out at constant volume, then `DeltaV=0.` Answer the following questions.
a) Give the equation for `DeltaU.`
b) 1000J was supplied to a system at constant volume. It resulted in the increase of temperature of the system from `45^oC` to `50^oC.` Calculate the change in internal energy.
