The General Gas Law is a combination of Boyle's Law, Amonton's Law and Charles' Law. It reads as follows:
P1 x V1 P2 x V2
_______ = ________
T1 T2
Here, T1 is the temperature at the first location, T2 is the temperature at the second. Temperature was originally measured in Rankine units, which is the temperature in Fahrenheit plus 460 (Absolute zero in Fahrenheit is -460 degrees), but now the more standard Kelvin units are used.
