| _______ Is the change of state from a solid to a gas without going through the liquid state | Sublimation |
| _______ Is the change if state from a gas to a solid without going through the liquid state | Deposition |
| The only substance that exists on Earth in all three states is _______ | Water |
| When you add ______ energy to ice, the temperature of the ice increases, which means that the ______ energy of the water molecules increases | Thermal-kinetic |
| At the ________ point of water (0) water molecules vibrate so fast that they begin to move out of their places and melting occurs | melting |
| Once a substance melts, the average ______ energy of its particles begins to increases again as more ______ energy is added. | Kinetic-thermal |
