- MELTING: Right arrow on the first horizontal segment (solid to liquid)
- FREEZING: Left arrow on the first horizontal segment (liquid to solid)
- CONDENSATION: Left arrow on the second horizontal segment (gas to liquid)
- EVAPORATION: Right arrow on the second horizontal segment (liquid to gas)

- A process where heat is released from the system into the surroundings. EXOTHERMIC
- A process where heat is absorbed by the system from the surroundings. ENDOTHERMIC
- A process that changes only the state, shape, size, and / or form of a substance. PHYSICAL CHANGE
- A process that changes the original substance into a new substance. CHEMICAL CHANGE

- MELTING: ENDOTHERMIC
- FREEZING: EXOTHERMIC
- EVAPORATION: ENDOTHERMIC
- CONDENSATION: EXOTHERMIC
- DEPOSITION: EXOTHERMIC
- SUBLIMATION: ENDOTHERMIC
