# Gay-Lussac's Law

on . Posted in Thermodynamics

Gay-Lussac's Law, one of the Gas Laws, states the proportional, that when temperature increases, pressure increases, when pressure decreases, temperature decreases.

## Gay-Lussac's Law formula

$$\large{ \frac { p_1} {T_1} = \frac { p_2} {T_2} }$$
Symbol English Metric
$$\large{ p_1 }$$ = pressure (use Kelvin) $$\large{\frac{lbf}{in^2}}$$  $$\large{Pa}$$
$$\large{ p_2 }$$ = pressure (use Kelvin) $$\large{\frac{lbf}{in^2}}$$ $$\large{Pa}$$
$$\large{ T_1 }$$ = absolute temperature (required for Gay-Lussac's Law) $$\large{ F }$$ $$\large{ K }$$
$$\large{ T_2 }$$ = absolute temperature (required for Gay-Lussac's Law) $$\large{ F }$$ $$\large{ K }$$
