How is the temperature of a body related to the speed of movement of its molecules?

According to the basic equation of the molecular kinetic theory of gas, the average kinetic energy Ek (cf) of the translational motion of molecules is determined by the formula: Ek (cf) = 3 * k * T / 2, where k is the Boltzmann constant, T is the absolute temperature.
The average kinetic energy of the translational motion of molecules is determined by the formula: Ek (avg) = m * Vav ^ 2/2, where m is the mass of the molecule, Vav is the mean square velocity of movement.
m * Vav ^ 2/2 = 3 * k * T / 2.
T = m * Vcr ^ 2/3 * k.
It can be seen from the formula that the absolute temperature T is directly proportional to the square of the average velocity of the translational motion of the molecules.
