Question

what happens to kinetic energy of the molecules of substance when it is cooled​

Answer 1

Explanation:

Explanation: This is because temperature is a measurement of the average kinetic energy of a substance. So, when you cool a substance, the temperature drops and makes the molecules move slower, lowering its KE. Because the molecules are more at rest, their potential energy increases.

Answer 2

So, when you cool a substance, the temperature drops and makes the molecules move slower, lowering its KE. Because the molecules are more at rest, their potential energy increases.
