Which energy form is associated with the random motion of particles and with temperature?

• A. Electrical Energy
• B. Kinetic Energy
• C. Thermal Energy
• D. Nuclear Energy

Answer: (C)

Temperature reflects the average kinetic energy of the particles in a material, and the random motions of those particles constitute a form of energy called thermal energy. As temperature rises, the particles move more vigorously on average, increasing the thermal energy they share. Electrical energy involves moving charges in a circuit, nuclear energy comes from forces inside the nucleus, and while kinetic energy describes motion, the energy tied to the random microscopic motion and temperature of a substance is thermal energy.
