Question

What happens to the kinetic energy of the molecules of a

substance when it is cooled?​

Answer 1

Answer:

kinetic energy decreases

Explanation:

hope you understood the answer

Answer 2

Answer:

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.
