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

Hello guys. I even know a thermal camera app which let us see the objects even in darkness. This is extremely important for travellers and hunters, for example. You can use it in your smartphone and with this app, your phone will function like a thermal imaging system. I think that's one more useful point in a smartphone.
