What is Meant by Combined Gas Law?

In Chemistry, combined gas law is the combination of Boyle’s law, Charles law, and Gay-Lussac’s law. This law has the relationship between the temperature, pressure and the volume. The combined gas law states that the ratio of the product of the pressure and the volume to the temperature. In this case, the system remains constant. The combined gas law formula is mathematically expressed by

K = PV/T


K is the constant

P is the pressure

V is the volume

T is the temperature.
