Combined gas law

Relates the pressure, volume and absolute temperature of a fixed amount of gas before and after a change in state. It combines Boyle's, Charles's and Gay-Lussac's laws into one relation.

\frac{P _{1} V _{1}}{T _{1}} = \frac{P _{2} V _{2}}{T _{2}}

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

What the symbols mean

$P_{1}$	initial pressure of the gas
$V_{1}$	initial volume of the gas
$T_{1}$	initial absolute temperature of the gas (in kelvin)
$P_{2}$	final pressure of the gas
$V_{2}$	final volume of the gas
$T_{2}$	final absolute temperature of the gas (in kelvin)
