10 joules of heat are transferred to a sample of ideal gas at constant volume. As a result, the internal energy of the gas
A) increases by 10 J
B) increases by less than 10 J
C) increases by more than 10 J
D) remains unchanged.

Question

Quizplus · Accepted Answer

For an ideal gas at constant volume, all the heat transferred to the gas goes into increasing its internal energy, hence the internal energy increases by the same amount as the heat transferred, which is 10 J.
