Charles / Gay-Lussac: V ∝ T at Constant p
At fixed p, V/T = nR/p = const. Record V, T, compute V/T, take mean or fit.
Goal
Estimate nR/p from the sample mean of V/T.
Equipment
- Piston, heater, gauge
Theory
V = nRT/p, so V/T = nR/p.
Procedure
- Heat the gas isobarically; log V, T, K.
Experiment
Conclusion
V/T is consistent with the fixed pressure.
