I was blown away at gravity shortage

Well. In layman terms, 1) Gas's thermal energy is: E=kT, k -some constant, T is a temperature in Kelvins 2) that thermal energy is roughly a kinetic energy at molecular level, i assume :), hence it is something like E = (mv^2)/2, m - molecule mass, v - its speed 3) so we have kT = (mv^2)/2 ==> ==> v = sqrt(2kT/m) this way it maybe more intuitive
