3. Phase Changes

4. Review: 3 Phases of Matter
Solid
Liquid
Gas

5. What happens during a phase change?
During a phase change, heat energy is either absorbed or released.
Heat energy is released as molecules slow down and move closer together.
Heat energy is absorbed as molecules speed up and expand.

6. Types of Phase Changes
Types of Phase Changes

7. Melting Phase change from a solid to a liquid
Molecules speed up, move farther apart, and absorb heat energy

8. Freezing Phase Change from a liquid to a solid
Molecule slow down, move closer together and release heat energy.

9. Vaporization (Boiling)
Phase change from a liquid to gas. It occurs at the boiling point of matter.
Molecules speed up, move farther apart, and absorb heat energy.

10. Evaporation Phase change from a liquid to a gas
Molecules speed up, move farther apart, and absorb heat energy.

11. Condensation Phase change from a gas to a liquid.
Molecule slow down, move closer together and release heat energy.

12. Sublimation Phase change from a solid to a gas.
Molecules speed up, move farther apart, and absorb heat energy.

13. Deposition Phase change from a gas to a solid.
Molecules slow down, move closer together and release heat energy.
