| Term | Definition |
|---|
| Solids | have a definite shape and volume and fixed closely packed arrangement of particles |
| 2 types of solids | Crystalline and Amorphous |
| Crystalline Solid | regular; or solids that are made up of crystals ex. salt sugar and snow |
| Amorphous solids | the particles are not arranged in regular patterns ex. plastics rubber and glass |
| liquid | definate volume but no shape |
| fluid | "a substance that flows" |
| Properties of liquid | Surface Tention and Viscosity |
| Surface Tention | the result of an inward pull closer together ex. water on a leaf |
| Viscosity | a liquids resistance to flowing; ex. honey (high viscosity) |
| Gas | no definate shape & volume; gas particles spread apart filling all the space available |
| Melting | the change from a solid to a liquid |
| Freezing | the change of state from a liquid to a solid |
| Vaporization | the change of state from a liquid to a gas |
| Evaporation | Vaporization that take place only on the surface of a liquid |
| Boiling | occurs when a liquid changes to a gas below its surface as well as at the surface |
| Condensation | the opposite of vaporization |
| Sublimation | occurs when the surface particles of a solid gain enough energy that forms a gas |
| Pressure | the force of its outward push divided by the area of the walls if the container |
| Boyle's Law | The relationship between the pressure and the volume of gas |
| Charle's Law | _found that when the temperature of a gas is increased at the constant pressure, its volume increases. When the temperature of a gas is decreased at the constant pressure,its volume decreases. |
| Graph | a diagram that tells how 2 variables, or factors that change, are related |
| Origin | the middle |
| Directly Proportional | when a graph of 2 variables is a straight line passing through the origin ..... |
| Vary Inversely | When a graph of 2 variables forms this kinda of curve..... |
| Pressure Formula | Pressure=Force/Area |
| Volume | the amount of space that matter fills |
| Temperature | a measure of the average energy of random motion of the particles of a substance |
