Which of the following is a direct cause of a substance’s temperature increase? a. energy is removed from the particles of the substance. b. kinetic energy is added to the particles of the substance. c. the number of atoms and molecules in a substance changes. d. the volume of the substance decreases.

Option (b) is the correct answer.

Explanation:

It is known that kinetic energy is the energy obtained by molecules of a substance. So, when molecules of a substance are in rapid motion then they have high kinetic energy.

And, relation between kinetic energy and temperature is as follows.

Hence, higher is the temperature of a substance more will be the kinetic energy of its particles.

Thus, we can conclude that kinetic energy is added to the particles of the substance is a direct cause of a substance’s temperature increase.
