If the substance changes its phase from solid to liquid or liquid to gas or solid to gas, it is endothermic process.
If the substance changes its phase from gas to liquid or from liquid to solid or from gas to solid, it is exothermic process.
Exothermic process is the process in which energy is released.
Endothermic process is the process in which energy is absorbed.
Sublimating is the process in which the phase changes from solid to gas.
Melting is the process in which the phase changes from solid to liquid.
Deposition is the process in which the phase changes from gas to solid.
Vaporizing is the process in which the phase changes from liquid to gas.
Condensing is the process in which the phase changes from gas to liquid.
Freezing is the process in which the phase changes from liquid to solid.
Sublimating, melting, and vaporizing are endothermic processes and deposition, freezing, and condensing are exothermic processes.
