Mr. Chang's class participated in a science experiment where they placed three substances outside in the sunlight to determine which substance would increase in temperature more quickly. How would the motion of the particles of each substance be described if they are allowed to sit in the Sun for a duration of 10 minutes? Choices:

The particles do not change in motion because the substances are undisturbed.

The particles of each substance begin to speed up and move farther apart as the temperature increases.

The particles of each substance begin to slow down and move closer together as the temperature increases.

The particles of each substance speed up and slow down simultaneously, but remain in a fixed position as the temperature increases
