Question

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 change in in internal energy of the system?​

Answer 1

Answer:

hey here is your answer

This is an isochoric process it means that volume is constant so deltaV=V2-V1=0 Hence q=deltaE so change in internal energy delta E=q=500joule

hope it help you

Answer 2

Answer:

At constant volume, ∆V = 0

Applying ∆U = q + w = q + P∆V

We get ∆U = q = 500J
