Worksheet: Isochoric


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 tyre contains 0.0460 m3 of air at a pressure of 7 . 1 0 × 1 0 5 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?

  • A 38.5 kJ
  • B 32.2 kJ
  • C 48.5 kJ
  • D 70.0 kJ
  • E 50.8 kJ
