14 Kinetic energy Energy possessed by an object in motion
15 (Phase change) Deposition - Gas to solid At night, it can get so cold that the water vapor in the air turns straight to ice
16 (Phase change) Condensation - Gas to liquid When water vapor molecules in the air get cold, they can turn into water
17 (Phase change) Boiling - Liquid to gas When liquid gold is heated enough it will become gaseous gold
18 (Phase change) Melting - Solid to liquid When iron is heated past its melting point, it become liquid iron
19 (Phase change) Evaporation - Liquid to gas When water is left out long enough, individual molecules break free and go into the air
20 (Phase change) Sublimation - Solid to gas When a solid is exposed to temperatures much higher that its boiling point, it becomes gas
21 (Phase change) Freezing - Liquid to solid When oil is cooled lower than its freezing point, it solidifies
