Question

which sentence best describes the relationship between thermal energy and the motion of particles? faster - moving particles always have lower thermal energy. thermal energy increases as particles move faster on average. particle motion is not related to thermal energy. slower - moving particles produce more thermal energy.

Explanation:

Thermal energy is related to the kinetic energy of particles. Faster - moving particles have more kinetic energy on average, which means higher thermal energy.

Answer:

Thermal energy increases as particles move faster on average.
