Which statement describes thermal energy?

a. the energy that is associated with electric fields.

b. the energy that is stored in chemical bonds.

c. the energy that is associated with the pull of gravity.

d. the energy that is associated with temperature.

Answer: Option (d) is the correct answer.

Explanation:

Thermal energy is defined as the internal energy of an object because of the kinetic energy present within the molecules of the object.

So, when thermal energy is added to an object then kinetic energy within its molecules will also increase. As a result, temperature of the object will also increase due to increase in number of collisions between the molecules.

Therefore, we can conclude that the statement energy that is associated with temperature, describes thermal energy.
