Question

Which is the best description of what happens when thermal energy is removed from a substance?(1 point)

Its particles gain kinetic energy and move more quickly.

Its particles lose kinetic energy and move more slowly.

It loses potential energy.

It gains potential energy.

Answer 1

Its particles lose kinetic energy and move more slowly.

Explanation: Removing thermal energy lowers temperature, which reduces the particles' kinetic energy and slows their motion.
