Worksheet: Isochoric

In this worksheet, we will practice relating the net work done on, the net heating of, and the change in the internal energy of gas at a constant volume.


The temperature of an ideal monatomic gas rises by 8.0 K while the volume of the gas remains constant. What is the change in the internal energy per mole of the gas?


A car tire contains 0.0460 m3 of air at a pressure of 7.10×10 Pa. How much more internal energy does this gas have than the same amount of gas at the same volume but at a normal atmospheric pressure? Consider air to be a diatomic gas.
