Question

Which is faster,hot or cold

Answer 1

A hot atom has higher kinetic energy than a cold atom. Thus a hot gas (that has a higher number of atoms with higher energy) will be faster in diffusion than a cold gas. A hot liquid faster than cold liquid and the vibrational energy of atoms in a solid is higher than those of a solid at a lower temperature.

Answer 2

Particles of matter are continuously moving, the have kinetic energy.
As the temperature rises the particles start moving FASTER .
