Deposition

Deposition is a process in which gas transforms into solid. The term is commonly used in the field of Physics and Chemistry. It is also known as desublimation.

Overview

Deposition is the opposite of sublimation, a process in which solid transforms into gas. It is a phase transition that occurs under certain conditions of temperature and pressure. Deposition is an exothermic process, which means it releases heat.

Process

During deposition, gas molecules lose energy. When they lose enough energy, they transition to the solid phase. The energy loss can occur due to cooling or due to a decrease in the volume of the system.

Applications

Deposition has many practical applications. It is used in the production of semiconductor devices, in the formation of frost and snow, and in the manufacturing of aerosol products.
