Gay–Lussac's Law

The pressure of a gas of fixed mass and fixed volume is directly proportional to the gas's absolute temperature.

The ratio of the initial pressure and temperature equals the ratio of the final pressure and temperature.

Formula

QuantityVariable[Subscript["P", "1"], "Pressure"]/QuantityVariable[Subscript["T", "1"], "Temperature"] == QuantityVariable[Subscript["P", "2"], "Pressure"]/QuantityVariable[Subscript["T", "2"], "Temperature"]

symbol description physical quantity
P1 initial pressure "Pressure"
T1 initial temperature "Temperature"
P2 final pressure "Pressure"
T2 final temperature "Temperature"
