1
Melting Solid Liquid Energy is added, particles speed up (endothermic) Melting Point: Temp. at which a substance melts Freezing Liquid Solid Energy is removed, particles slow down (exothermic) Freezing point: temp at which a substance freezes Boiling Liquid Gas Throughout a liquid Boiling Point: Temp at which a liquid boils Endothermic
2
Evaporation Liquid Gas Only at surface Endothermic Condensation Gas Liquid Exothermic Ex: Water droplets on glass Sublimation Solid Gas Endothermic *Dry Ice*
