    the speed of a molecule is proportional to the square root of the temperature of the gas to which that molecule belongs to, namely the quadratic mean velocity is given by the subsequent formula: \[\Large {v_{RMQ}} = \sqrt {\frac{{3RT}}{M}} \] where R is the gas constant, T is the absolute temperature, and M is the molecular mass of a gas
