200 joules of heat was supplied to a system at constant volume. It resulted in the increase in temperature of the system from 29R 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
Correct Answer
Option B
Detailed Explanation
At constant volume, ΔV = 0, so w = -PΔV = 0. Therefore, the change in internal energy U = q = 200 J.
