Melting-The change of state from a solid to a liquid. Adding energy
Melting point-The temperature at which matter changes from a solid to a liquid.
Melting is an endothermic change.
Freezing-The change of state from a liquid to a solid. Remove energy
Freezing is an exothermic change.
The temperature for freezing point and melting point is the same.
Evaporation-The change of a substance from a liquid to a gas.
Evaporation can occur at the surface of a liquid that is below its boiling point.
Boiling-The change of a liquid to a vapor, or gas, throughout the liquid.
Boiling Point-The temperature at which a liquid boils.
Changes in Atmospheric air pressure affects boiling point and freezing point temperatures.
Condensation-The change of state from a gas to a liquid.
Condensation is an exothermic change.
Sublimation-Change of state in which a solid changes directly into gas.
