Answer: A) As the temperature increases, the kinetic energy of the molecules increases.

Explanation:

Kinetic energy is the energy of a moving object. Molecules in a substance have a range of kinetic energies because they do not all move at the same rate. At the moment when the material absorbs energy, the particles move faster, so that the average kinetic energy, and thus the temperature, increases.
