As the liquid loses heat to its environment, the particles slow down and eventually stay place and only vibrate.
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.
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.
Gases condense into liquids when the temperature of the environment decreases.

- Dew on grass
The evaporation of water from leaves
through the stomata (holes) on the underside of the leaf.
A solid changing directly into a gas
Example: Dry ice (solid CO2) changes to a gas
A gas changing directly into a solid is called deposition.
Example: Frost on a window pane
