Solid Liquid and Gas
| Term | Definition |
|---|---|
| Solid | A state of matter that has a definite shape and a definite volume. |
| Crystalline Solid | A solid in which the atoms are arranged in a regular, repeating pattern. |
| Amorphous Solid | A solid made up of particals that are not arranged in a regular pattern. |
| Liquid | A state of matter that has not defined shape but has a defined volume. |
| Fliud | Any change in which energy is released. |
| Surface Tension | The result of an inward pull among the molecules of a liquid that brings the molecules on the surface closer together; causes the surface to act as if it has a thin skin. |
| Viscosity | A liquid's resistance to flowing. |
| Gas | A state of matter with no defined shape or volume. |
| Pressure | The force pushing on a surface divided by the area of that surface. |
| Melting | The change in state from a solid to a liquid. |
| Melting Point | The temperature at which a substance changes from a solid to a liquid; the same as the freezing point, or temperature at which a liquid change to a solid. |
| Freezing | The change in state from a liquid to a solid. |
| Vaporization | The change of state from a liquid to a gas. |
| Evaporation | The process by which molecules at the surface of a liquid absorb enough energy to change to a gas |
| Boiling Point | The temp at which a liquid boils. |
| Condensation | The change of state from a gas to a liquid. |
| Sublimation | The change in state from a solid directly into a gas without passing through the liquid state. |
| Charles's Law | A principle that describes the relationship between the temp and volume of a gas at constant pressure. |
| Directly Proportional | A term used to describe the relationship between two variables whose graph is a straight line passing through the point. |
| Boyle's Law | A principle that describes the relationship between the pressure and volume of a gas at constant temperature. |
| Inversely Proportional | A term used to describe the relationship between two variables whose product is constant. |
