The Ideal Gas Law

By combining Boyle's law and Charles' law, we find that:

PV = KT

for an ideal gas at any temperature, pressure or volume,

where:

The ideal gas law states that the constant, K, is equal to the number of molecules of gas present (expressed in moles) times a constant R.

R is called the Universal Gas Constant.

This gives us the formula:

PV = nRT

where:

When we use the following unit system:

Then R = 62.37 in units of (L*mmHg / mole*K)
