Gas Temperature - NASA

In a hot gas, the molecules move faster than in a cold gas; the mass remains the same, but the kinetic energy, and hence the temperature, is greater because of the increased velocity of the molecules. Turning to the large scale, the temperature of a gas is something that we can determine qualitatively with our senses.
