The document discusses the four phases of matter: solids, liquids, gases, and plasma. It describes the properties of each phase, including how tightly or loosely packed the particles are and whether they have a definite volume and shape. It also explains the different types of phase changes that can occur as matter transitions between phases, such as melting, freezing, boiling, condensing, sublimating, and depositing.

2. Phases of MatterSolids – Tightly packed particles, particles are locked.

3. Phases of MatterSolids – Tightly packed particles, particles are locked.Liquids – Loosely packed particles, particles can slide past each other (flow).

4. Phases of MatterSolids – Tightly packed particles, particles are locked.Liquids – Loosely packed particles, particles can slide past each other (flow).Gases – Particles are spaced apart (a lot of space between them), particles can flow.

5. Phases of MatterSolids – Tightly packed particles, particles are locked.Liquids – Loosely packed particles, particles can slide past each other (flow).Gases – Particles are spaced apart (a lot of space between them), particles can flow.Plasma – High energy gas particles that have had their electrons ripped off.
