Answer:
Thermal energy added: sublimation, evaporation, melting
Thermal energy removed: condensation, freezing, deposition
Explanation:
Condensation is the process by which water vapor (gas) cools down and forms liquid water. This can be seen in nature when clouds are formed, and it rains. This process involves the loss of thermal energy.
Freezing is the process by which water is cooled from a liquid state, to a solid state. This occurs in nature at the polar regions where the temperatures are below 0 degrees Celsius.
Deposition is the process where a gas turns into a solid, without passing through a liquid phase. This can be seen when carbon dioxide gas is cooled, and it goes straight to a power (solid).
Sublimation is the process where a solid turns into a gas, without passing through a liquid phase. This process is the opposite of deposition, and it occurs when a lot of thermal energy is added to a substance.
Evaporation is the process of where single water molecules phase change to gaseous form when they gain energy, and naturally occurs.
Melting is a process of a solid, changing to a liquid. This requires an energy input.
