e Phase Changes Review: 3 Phases of Matter Solid Liquid Gas

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. Types of Phase Changes Types of Phase Changes Melting

Phase change from a solid to a liquid Molecules speed up, move farther apart, and absorb heat energy Freezing Phase Change from a

liquid to a solid Molecule slow down, move closer together and release heat energy. 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. Evaporation

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

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

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

Molecules slow down, move closer together and release heat energy. Boiling Point Boiling Point: The temperature at

which a liquid changes into a gas. 212 F 100 C For Water

Melting Point Melting Point: The temperature at which a solid changes into a liquid. Freezing point: The temperature at which a liquid changes into a solid Graphing a Phase Change
