FREEZING
As the liquid loses heat to its environment, the particles slow down and eventually stay place and only vibrate.

MELTING
Solids absorb heat from the environment, the particles start to move apart from each other and slide pass one another.

The melting point and freezing point are the same temperature.

EVAPORATION
Heat causes the particles (on the surface of a liquid) to change from a liquid to a gas.

The hotter it is, the faster this will happen.

CONDENSATION
Gases condense into liquids when the temperature of the environment decreases.

Examples:
- The outside of a cold cup
- Dew on grass
- Clouds

TRANSPIRATION

The evaporation of water from leaves
through the stomata (holes) on the underside of the leaf.

SUBLIMATION
A solid changing directly into a gas

Example: Dry ice (solid CO2) changes to a gas

DEPOSITION
A gas changing directly into a solid is called deposition.

Example: Frost on a window pane
