All the molecules of a substance possess the "average kinetic energy" value. true false

The given statement is true.

Explanation:

Average kinetic energy is defined as the sum of rotational, translational, and vibrational energies possessed by the molecules of a substance.

This energy is present in a substance because of the movement of its particles. This means that a substance whose molecules move from their initial position will possess average kinetic energy.

For example, when molecules of a solid substance is vibrating so, it means they are possessing average kinetic energy.

Thus, we can conclude that the statement all the molecules of a substance possess the "average kinetic energy" value, is true.

there is none because earth is stationary and flat.
