and here are the numbers just in case 250, 273, 273, 298

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

yes:) so how can we calculate? :/ what do we plug in?

we have to pick the gas with the highest temperature

oops. sorry, we have to pick the object with the littlest temperature
