Question

what happens to the motion of particles of a substance when temperature increases or decreases? particles remain stationary regardless of temperature changes. an increase in temperature causes particles to move faster, while a decrease in temperature causes them to move slower. particles move in a circular motion when temperature changes. temperature changes do not affect particle motion at all.

Explanation:

Temperature is a measure of the average kinetic energy of particles. Higher temperature means more kinetic energy and faster - moving particles, while lower temperature means less kinetic energy and slower - moving particles.

Answer:

An increase in temperature causes particles to move faster, while a decrease in temperature causes them to move slower.
