For a phase change to occur heat energy must be added to or removed from water molecules. The gaseous substance gets deposited (usually as crystals) bypassing the intermediate liquid state. When energy is removed from matter, the atoms or molecules move slower and closer together.

Like other physical processes, deposition will involve either input or emission of thermal energy.
An exothermic process releases heat, causing the temperature of the immediate surroundings to rise.
We have seen that vaporization requires heat transfer to a substance from its surroundings. How do you know if a process is exothermic or endothermic? The process of deposition, where a gas transitions directly into a solid, releases latent heat. Deposition in chemistry is a phase transition process where a gas transforms directly into a solid without passing through the liquid phase.
In chemistry, deposition occurs when molecules settle out of a solution. Matter either loses or absorbs energy when it changes from one state to another. This happens because, during this phase change, the gas loses energy as it forms. The energy change is typically a change in heat (thermal energy).

Understanding whether deposition is endothermic (requiring heat absorption) or exothermic (releasing heat) has practical implications in numerous fields, from materials.
In chemistry, deposition refers to the process in which a gas changes directly to a solid without going. Deposition is when a substance in gas form changes states to become a solid. Too low a deposition temperature can lead to insufficient layer formation, poor adhesion or low density, while too high a temperature can lead to undesirable phase transitions, thermal. Deposition and slagging are common phenomena on furnace walls which cause increased thermal resistance and a decreased in the absorption of heat by the water wall,.
Instead, it is exothermic, meaning it releases heat. Deposition is a phase transition in which a gas transforms directly into a solid without passing through the liquid phase. No, deposition does not require heat. However i am not sure of this?

The formation of water droplets and ice.
This phenomenon is commonly observed in nature,. I would assume that since it is undergoing deposition, it would just be a slope from the gaseous state to the liquid state. This increases the density of the matter and causes the substance to change.
