Thermal velocity of a substance is equal to the measure of temperature of the substance (solid, liquid and gas). Thermal velocity is the velocity or thermal motion of the particles of a substance. Thermal velocity of a gas or a liquid or a solid is not a vector quantity but it is a scalar quantity. It is the root mean velocity of the particles of the substance. The thermal velocity of particles can be measure by formula;
Vrms= [kB T/ m]1/2
Vrms= Root mean square velocity
kB= Boltzmann constant
T= temperature
m= mass
Vrms= [kB T/ m]1/2
Vrms= Root mean square velocity
kB= Boltzmann constant
T= temperature
m= mass
