The process of deposition is a phase transition in which a gas changes directly into a solid without passing through the liquid phase. During deposition, the gas molecules lose energy and slow down. As a result, they come closer together and arrange themselves in a structured, solid form. This transition occurs when the temperature of the gas decreases significantly, causing the particles to lose kinetic energy and form a solid lattice. Deposition is responsible for various natural phenomena, such as the formation of frost on surfaces during cold weather, and it also has practical applications in fields like semiconductor manufacturing.
