Lesson 4 Study Guide

In which phase of matter are particles the most closely packed?

• Solid

• Liquid

• Gas

• Plasma

What happens to particles when a substance goes from a solid to a liquid?

• The particles move farther apart and start to move more freely.

• The particles stop moving entirely.

• The particles become more tightly packed.

• The particles change into different elements.
