Solids liquids and gasses
| Question | Answer |
|---|---|
| Surface tension | A result of an inward pull among the molecules of a liquid that brings the molecules on the surface closer together |
| Viscosity | A liquids resistance to flowing. |
| Gas | This type of matter has no definite shape or volume. |
| Melting | The physical change of state from a soild to a liquid. |
| Melting point | The temperature at which a solid turns into a liquid. |
| Freezing point | The temperature at which a liquid changes to a solid. |
| Vaporization | This change in state takes place when the particles in a liquid gain enough energy to form a gas. |
| Evaporation | This type of vaporization takes place on the surface of a liquid only. It is a slow process. |
| Boiling | This type of vaporization occurs when you see bubbles below the surface of liquid. The vaporization occurs all through the liquid. A rapid type of vaporization. |
| Boiling point | The temperature at which a liquid becomes a gas. |
| Sublimation | This change in state occurs when the surface particles of a solid gain enough energy to become a gas. |
| Volume | The amount of space matter takes up. |
| Temperature | The measure of the average random motion of the parcticles of a substance. Use a thermometer and let the particles of the liquid in it reach the same speed as the substance you are measuring. Scientists use Celsius Degrees. |
| Pressure | Gas particles pushing against the walls of a container causes this. Pressure is found by dividing the force by the area. P = F / A . |
| Boyles law | The relationship between the pressure and the volume of a gas. If the pressure is increased then the volume decreases. Vise versa If the volume is increased then the pressure is decreased. |
| Charles law | This law states that when the temperature of a gas is increased at constant pressure, its volume increases. This is a direct relationship between temperature and volume. |
| Graph | A diagram that tells how two variables are related. (Independent and dependent.) |
| Origin | The 0,0 point on a graph. Where the line begins. |
| Vary inversly | One variable goes up while the other goes down. When graphed it shows a curved line that starts high on the y axis and ends up horizontal to the x axis. |
| Direct relationship | A relationship between two variables where if one increases the other one increases. |
| Solid | a phase of matter that has a definite shape and a definite volume |
| Liquid | A phase or state of matter that has a definate volume but no definite shape. |
| Fluid | A phase or state of matter that has a definate volume but no definite shape. |
| Crystaline solid | A type of matter whose particles have a definate arrangment. |
| Amorphous solid | A type of matter whose particles have no definate arrangment. |

| Freezing | The physical change of state when a a liquid turns into a solid. |
| Condensation | The physical change in state that occurs when a gas turns into a liquid. |
