Sublimation- The particles of a solid do not pass through the liquid as they form a gas. It occurs when the surface particles of the solid gain enough energy that they form a gas. Also when certain temperatures are low and there is snow, it might seem to dissapear but sometimes when the snow is about to melt it turns into gas because its to cold to melt. An example would be dry ice. It's the transition of a substance from the solid phase to a gas phase. It's a change between a solid and a gas.

Evaporization- It is vaporization that takes place only on the surface of a liquid. An example would be a shrinking puddle, because the puddle gains energy from the ground, the air, or the sun. All the added energy helps some of the water molecules in the surface of the puddle to escape in the air or evaporate. When water is converted from its liquid form to its vapor form and goes from land and water to the atmosphere.

Condensation- This is the opposite of vaporization and it occurs when particles in a gas lose enough thermal energy to form a liquid. An example would be the water vapor from a hot shower that contacts the cool surface of a bathroom mirror and forms a liquid or when water vapor in the air condences into liquid dropsforming clouds. When the drops get heavy enough it causes them to drop forming rain. It's a chemical reaction in which two molecules combine to form one single molecule.


Vaporization- Vaporization is the change from a liquid to a gas. It takes place when the particles in the liquid gain enough energy to form a gas. The two types of vaporization are evaporation, and boiling. For vaporization to happen you need heat.Boiling- Boiling occurs when a liquid changes to a gas below its surface as well as at the surface. It's another kind of vaporization. An example is a pot over a hot stove, filled with water thats bubbling. The temperature of liquid boils is called its boiling point. The boiling point of a liquid depends on the pressure of air above it.

Melting- Melting is the change in state from a solid to a liquid. In most pure substances melting occurs at a specific temperature called, the melting point. An example of melting would be ice cream by the hot sun. The melting point is a characteristic property of a liquid. The melting point of pure water is zero degrees celsius.

Freezing- Freezing is the change of state from a liquid to a solid. At it's freezing temperaturethe particles of a liquid are moving so slowly that they begin to from a regular pattern. An example would be an ice cube. When you put water into a freezer the water loses energy to the cold air into the freezer and begins to freeze forming ice.
