Gas Lab — Ideal Gas Laws and Kinetic Theory for A Level Physics

Build your own gas-law investigation in Free Lab. Drag a piston, lock variables, compare molecular speeds, record graphs and export results, with guided AQA and OCR A Level experiments and challenges.

Learning guide and suggested activities

What this tool shows

Try these tasks

  • Hold temperature constant and halve volume. What happens to pressure?
  • Keep pressure constant and double temperature. What happens to volume?
  • Link the average kinetic energy of particles to temperature.
