Answer:

D. Thermal energy increases as the atoms and molecules in a system move more.

Explanation:

Thermal energy is a form of kinetic energy possessed by molecules of a system. The measure of this kinetic energy in an atom is called heat.

The average kinetic energy of a system is the temperature.

  • According to the kinetic theory, the more the particles move, the more their thermal energy.
  • Thermal energy is often predicated on the velocity of the particles of the medium.
