Changes: Solid and Liquid

Melting: Solid → Liquid

Melting point: Temperature When melting occurs

• Big Idea: When a substance melts, the particles in the solid vibrate so fast that they break free from their fixed positions.

Changes between Liquid and SolidFreezing: Liquid → Solid

Freezing point: Temperature When freezing occurs

•Big Idea: When a substance freezes, the particles in the liquid move so slowly that they begin to take on a fixed positions.

True of False

Melting and freezing are reversible physical changes of matter.

True

Changes: Liquid and GasVaporization: Liquid → Gas. Takes

place only on the surface of the liquid.

Boiling: Liquid → Gas. Occurs when liquid changes to gas below the surface of the liquid as well as at the surface.

Boiling Point: Temperature at which liquid boils.

+ Thermal Energy→

Changes between Liquid and Gas

•Condensation: Gas → Liquid.

• Big Idea: During condensation, the particles loose enough thermal energy to form a liquid.

- Thermal Energy

→

Sublimation: Solid → Gas. During Sublimation, particles

of a solid do not pass through the liquid state as they form a gas.

When dry ice becomes gas, it cools water vapor in the nearby air. The water vapor then condenses into a liquid, forming fog around the dry ice.
