|---|---|
| the change from a solid to a liquid | melting |
| the change from a liquid to a solid | freezing |
| the change from a liquid to a gas | vaporization |
| the temperature at which a substance boils | boiling point |
| is the vaporaation that occurs at the surface of a liquid below its boiling point | evaporation |
| a substance changes from one physical state to another | change of state of matter |
| energy is removed | exothermic |
| change of state from a gas to a liquid | condensation |
| the product of vaporation of liquid water | steam |
| energy is added | enodothermic |
| condensation is an example of a endothermic OR exothermic change | exothermic |
| the change of state from a solid ddirectly to a gas | sublimation |
| melting is an example of a endothrmic OR exothermic change | endothermic |
| freezing is an example of an endothermic OR exothermic change | exothermic |
| sublimation is an example of an endothermic OR exothermic change | endothermic |
