SolutionPutting together 2 or more substances that cannot be easily separated.
PropertyIt describes how an object looks, feels, or acts.
Melting pointThe temperature at which a solid becomes a liquid, this happens when a solid is heated. (Energy is added)
CondensationWhen vapor or gas cools and changes to a liquid.
Boiling pointTemperate at which a liquid becomes a gas or vapor.
EvaporationWhen a liquid changes to a gas. Heat makes water evaporate faster.
Freezing pointThe temperate when a liquid becomes a solid.
GasA state of matter whose atoms have a lot of energy (move quickly) and do not have a definite shape, mass or volume.
LiquidA state of matter whose atoms have more energy than a solid and less energy than a gas. It does not have a definite shape. Atoms are close together and move around.
