# What is The Ideal Gas Law?

The ideal gas law incorporates the relationship between pressure, volume, amount of (number of moles) gas, and the temperature of the gas. It is written pV = nRT, where R is the Universal gas constant.

p = pressure, V = volume, n = number of moles, T = temperature.

For calculations, the units must be:

p = Pa, V = m³, n = mol, R = J/(mol.K), T = K
