Phase Changes

Deposition occurs when a gas turns into a solid, skipping the liquid phase.
Freezing occurs when a liquid loses energy or gains pressure and turns into a solid.
Condensation occurs when a gas cools into a liquid.
Evaporation occurs when a liquid turns into a gas.
Sublimation occurs when a solid turns straight into a gas.

Phase Characteristics

Solids have atoms and molecules that are closer together, allowing for a definite shape and size.
Gases have no definite shape, regardless of the container.

Phase Change Concepts

A phase change is a change in the state of a substance from one phase to another.
Melting occurs when a solid becomes a liquid, typically when it gains energy or heat.
The triple point is the temperature and pressure at which a substance can exist in all three phases (solid, liquid, and gas) simultaneously.

Slow Phase Changes

Evaporation occurs slowly over time when a liquid turns into a gas.

Phase Change Processes

Sublimation is the process in which a solid skips the liquid stage and phases directly into a gas.
Condensation occurs when water vapor condenses on dust to create clouds.

Environmental Factors

The main factor that causes lakes and rivers to freeze in the winter is low temperature.
Deposition occurs when a gas turns directly into a solid, skipping the liquid stage.
