Ideal gas law
The ideal gas law relates absolute pressure, occupied volume, amount of gas, and kelvin temperature. The forms using moles and using particle count express the same state relationship with different constants. For example, heating a fixed amount of ideal gas in a rigid sealed container raises its pressure.
