The Ideal Gas Law

The Ideal Gas Law

The ideal gas law relates the variables of pressure, volume, temperature, and number of moles of gas within a closed system.


The ideal gas law takes the form:

PV = nRT

P = Pressure of the confined gas in atmospheres

V = Volume of the confined gas, in liters

n = Number of moles of gas

R = Gas Constant, 0.0821 L·atm/mol·K

T = Temperature in Kelvin
