Compress, heat, and test the Ideal Gas Law

Lock one variable to isolate Boyle's, Charles's, or Gay-Lussac's Law, then verify each relationship with PV = nRT.

StatusStable
1

Boyle's Law: Lock temperature. Halve the volume — does pressure double? Verify P₁V₁ = P₂V₂.

2

Charles's Law: Lock pressure (adjust V to maintain ≈1 atm). Heat the gas — does volume scale with temperature (K)?

3

Gay-Lussac's Law: Lock volume. Change temperature and confirm P/T stays constant. Record both trials.

Lab task

Complete all three named gas laws using the lock buttons. For each, record before and after values and verify the ratio stays constant.

Key principle

All three named laws (Boyle, Charles, Gay-Lussac) are special cases of PV = nRT where one variable is held constant. Absolute temperature (Kelvin) must always be used.

Mission

What to prove in this lab

  1. Relate pressure, volume, temperature, and amount of gas using live measurements.
  2. Predict how compression and heating affect particle motion and pressure.
  3. Use PV = nRT to compare different gas chamber setups.
