How do solids and gases change state?
By sublimation: The change from a solid state directly into
 a gas is called sublimation. As the particles of solid dry ice
gain energy their motion completely overcomes the attraction
 between the particles, and the particles escape into the air as gas.

By deposition: is the change in state from

 a gas directly to a solid. Deposition

 is the process by wich ice crystals form in clouds.

 How do liquids and gases change state?
By evaporation:
As a liquid is warmed, its particles gain energy. Some particles gain enough
 energy that they escape from the surface of the liquid and become gas.

By boiling: A rapid change from a liquid to a gas. 

This changes takes place throughout a liquid, not just at the surface.

 The specific temperaturenat which this

 occurs in a liquid is called boiling point.

By condensation: the attraction bbetween particle

s overcomes the speedof their motion, and a liquid forms.

 This change is called condensation. 

 How do solids and liquids change states?
 By freezing: the change in state in wich a liquid becomes a solid is called freezing. The temperature at wich a liquid substance changes into a solid is the liquid´s freezing point.

By melting: the particles are able to slide past one another. 

This change is called melting.

 What happens when substances change state?
 Ice, liquid water and water vapor are different states of the same substance

 Shape up:
All solid substances has a definite shape and volume. The particles in a solid are fixed positions and are close together. A solid can´t easily change in shape or volume. You can change the shape of a solid by breking it into pieces.

the water would take the shape of the container. The water would have the same volume as the container. All liquids have a definitive volume but no definite shape. The particles in a liquid are close together, but they are not tightly attached to one another. 

Gases do not have a definite volume or shape. The particles in a gas are very far apart compared to the particles in a solid or a liquid. The amount of space between the particles in a gas can change more easily.

Gas: it doesn´t have a definite volume or shape. Its particles move freely.

Liquid: a substance that has a definite volume but not shape, it adopts the shape of its container. The particles are clase together but not in a fixed position so they can move from one place to another.
