Question

What is temperature on a molecular level?

Answer 1

At the molecular level, temperature is related to the random motions of the particles (atoms and molecules) in matter. Because there are different types of motion, the particles' kinetic energy (energy of motion) can take different forms, and each form contributes to the total kinetic energy of the particles.

Answer 2

At the molecular level , Temperature is related to the random motions of a particles ( atoms and molecules ) in matter .
