Question

What happens when the thermal energy of a substance increases?

The motion of the particles in the substance increases, and the temperature of the substance decreases.
The motion of the particles in the substance decreases, and the temperature of the substance increases.
Both the motion of the particles in the substance and the temperature of the substance decrease.
Both the motion of the particles in the substance and the temperature of the substance increase.

Answer 1

Both the motion of the particles in the substance and the temperature of the substance decrease.

Step-by-step explanation:

The hotter the substance the more kinetic energy the particles gain which can result in more collisions in the substance.

Answer 2

both the motion and the temperate increases because the particles have more kinetic energy
