Question

how does the kinetic energy of a molecule in a substance change with the decrease in its
tempreture
​

Answer 1

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.

Answer 2

Explanation:

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 moleculesare more at rest, their potential energy increases
