Ideal (general) gas law

The ideal gas law, also known as the general gas equation, is an equation that explains the relationship between temperature, volume, and pressure of a hypothetical ideal gas. It states that the pressure of a gas is proportional to its temperature (in Kelvin) and inversely proportional to its volume. The equation is PV = nRT where P is pressure, V is volume, n is moles, R is the gas constant, and T is temperature.
