Phase Changes
| Question | Answer |
|---|---|
| vertical distance, or elevation, above sea level. | Altitude |
| change from a liquid to a gas | Boil |
| the temperature at which boiling occurs | Boiling Point |
| Change from a liquid to a solid | Freeze |
| The temperature at which freezing occurs. | Freezing Point |
| A phase in which matter has no definite shape or volume | Gas |
| will expand to fill any container; can be compressed; molecules relatively far apart and move freely. | Gas Properties |
| water in the gas phase. | Water Vapor |
| a phase in which matter has definite volume but no definite shape. | Liquid |
| Will take the shape of a container, but cannot expand, or be compressed; molecules in a liquid move randomly but stay close to one another | Liquid Properties |
| Change from a solid to a liquid | Melt |
| The temperature at which melting occurs. | Melting point |
| a state of matter with certain physical properities | Phase |
| a phase in which matter has a definite shape and a definite volume | Solid |
| will retain the same shape and volume in any container; atoms are held in a rigid structure and can not move freely | Solid Properties |
| Water in the solid phase. | Ice |
| Energy in the form of heat. | Thermal Energy |
| Rapid change from liquid to a gas. | Vaporization |
| change from a gas to a liquid | Condensation |
| change from a solid to a gas | Sublimation |
| slow change from a liquid to a gas | Evaporation |
| change from a gas to a solid | Deposition |
