Frazer does Physics: 5.18 Gay-lussac's law

November 20, 2011

5.18 use the relationship between the pressure and Kelvin temperature of a fixed mass of gas at constant volume:

$\frac{p_{1}}{T_{1}} = \frac{p_{2}}{T_{2}}$

p₁= Pressure at the beginning

T₁ = Absolute temp at the beginning

p₂ = Pressure at the end

T₂ = Absolute temp at the end

NB: The units of temperature must be Kelvin, but any unit of pressure can be used

Pressure is directly proportional to absolute temperate (when gas is at a constant volume)

$p\propto T$
