Always use atmosphere for pressure, liters for volume, and Kelvin for temperature. What kind pressure units are used for the gas laws? The relation works best for gases held at low pressure and ordinary temperatures. 46.1 g/mol b. If the absolute temperature of a gas is tripled, what happens to the root-mean-square speed of the molecules? This law holds true because temperature is a measure of the average kinetic energy of a substance; when the kinetic energy of a gas increases, its particles collide with the container walls more rapidly and exert more pressure.
