deposition

Deposition is the process by which a gas changes directly into a solid without passing through the liquid state. It occurs when particles in a gas lose enough energy to settle into a solid form, such as frost forming on a cold surface. This process is the reverse of sublimation, where solids turn directly into gases. Deposition often happens in nature, like frost in winter, and plays a role in various industrial applications. It involves changes at the molecular level driven by temperature and pressure conditions that favor the solid state.
