The ideal gas law describes a relationship between the pressure, volume, temperature, and amount of a ideal gas.

The ideal gas law is represented by the equation:

PV = nRT

Where: 

P represents the pressure of the gas, 

V represents the volume of the gas, 

n represents the number of moles of the gas, 

R is the ideal gas constant, and 

T represents the temperature of the gas in Kelvin.
