Physics: AQA GCSE Higher, topic 3.3.4
Work Done on a Gas
Doing work on a gas increases the gas’ internal energy. This increases the temperature of the gas. We can do work on a gas with a bicycle pump.

Gas applies pressure
- The gas applies pressure (and so a force) to the pump’s plunger.

Do work on the gas
- You must work against this force to push the plunger down.

Increase kinetic energy and temperature of gas
- This work increases the kinetic energy and temperature of the gas.
