### Solids, Liquids and Gases

1. 1. Solids, Liquids and Gases By Andrina
2. 2. Solids Liquids and Gases How strong are the attractive forces in solids, liquids, and gases? How are the participles arranged in solids, liquids and gases? What is the movement in solids, liquids and gases? The particles in a solid are very close together, they move slowly. The shape of a solid is always a specific shape. They have very close attraction. The particles in a liquid are not to close but not to far apart, they move pretty fast but not as fast as a gas. The shape of the liquid is the shape of the beaker. The attraction is medium attraction. The particles of a gas are very far apart, they move very fast. The gas does not have a shape. They have no attraction at all.
3. 3. Solids, Liquid and Gases What are the three phases of matter? Solids, Liquids and Gases Solid Liquid Gas
4. 4. Solids Liquids and Gases What has to happen in order to get a phase change? You have to add energy. You take away energy to get it back to a solid.
5. 5. Solids Liquids and Gases What has to happen in order to give us pressure? The gas particals hit the side of an object.For example a box with gas inside would blow the cap of the box.
6. 6. Solids Liquids and Gases What happens when we heat Solids Liquids and Gases? When we heat up a solid it turns into a liquid. After a while it starts to boil and the gas comes out. Heat makes the particles move faster. For example:
7. 7. Solids Liquids and Gases Why do solids, liquids, and gases expand when we heat them up? They expand because when you heat a solid, liquid or gas the heat tears the molecules apart, which means they can move more.
8. 8. Solids, Liquids and Gases What is melting, boiling, freezing, vaporization, condensation, and sublimation? Melting=The temperature at which a solid turn into a liquid. Boiling=The temperature at which the liquid boils. Freezing= The temperature at which a substance changes from a liquid into a solid. Vaporization= The change of a substance from a liquid to a gas. Condensation=A gas turns into a liquid. Sublimation=A solid turning directly into a gas.
