Question

On cooling down substance there is a loss of heat and kinetic energy of it's molecules.
a) increase
b) decrease​

Answer 1

Answer:

Removing energy (cooling) atoms and molecules decreases their motion, resulting in a decrease in temperature. Temperature is a measure of the average kinetic energy of the atoms or molecules of a substance. Heat is the transfer of energy from a substance at a higher temperature to a substance at a lower temperature.
