Sort them by Thermal energy added, Thermal energy removed. condensation freezing deposition sublimation evaporation melting

Thermal energy added means that heat is added to the system to allow the reaction to occur. Processes that undergo this type of reaction are freezing, deposition and sublimation. Thermal energy removed means that heat is released from the system to the surroundings to allow for the reaction to occur. Processes that undergo this type of reaction are condensation, evaporation and melting
