Boyle's Law: PV at Constant T

Isothermal: PV = nRT. Record P and V; fit or mean the product PV.

School· 20 min·Related simulator: Gas Laws Interactive

Goal

Verify that PV is constant (within noise) for a fixed amount and temperature.

Equipment

  • Piston, manometer

Theory

Ideal gas isotherm: pV = nRT = constant for fixed n, T.

Procedure

  1. Change V; read P.

Experiment

Conclusion

Mean PV matches nRT of the sim.
