Sublimation is an endothermic process because it requires energy to break the bonds between the particles and change the substance from solid to gas. Deposition, on the other hand, is an exothermic process because it releases energy as the substance changes from gas to solid. Condensation is also an exothermic process, as it releases energy when gas particles come together to form a liquid.
