In Film 5, a colder model is considered. The number of atoms is kept the same (900) but the number of quanta is reduced from 900 to 300 (N atoms sharing q = N/3 quanta). Film 5 runs the game until an equilibrium is reached. The ratio between the number of atoms with n quanta and (n + 1) quanta is now R = 4. This ratio can be taken as a measure of temperature. The larger the ratio, the colder is the object.
