Unit 1-Matter

A student leaves a bowl of ice cream on a table, where it turns to a liquid. The student places the liquid ice cream back into the freezer overnight. How do the motion of the particles in the ice cream change when it is placed in the freezer?

• the particles slow down and move closer together

• the particles speed up and move closer together

• The particles slow down and move farther apart

• the particles speed up and move farther apart
