Key Concepts

Phase Transition

Phase transitions refer to the processes by which a substance changes from one state of matter to another (solid, liquid, or gas). These transformations involve energy changes and alterations in the arrangement and movement of particles within the substance, and they are influenced by variables such as temperature and pressure.

Deposition

Deposition is a phase transition in which a substance moves directly from the gaseous phase to the solid phase without passing through the liquid phase. This process typically occurs under conditions of decreased temperature or increased pressure, leading to the release of latent heat as the substance solidifies.

Sublimation

Sublimation is the phase transition where a substance changes directly from the solid phase to the gaseous phase without first becoming a liquid. This endothermic process involves the absorption of energy to overcome the forces holding the particles in the solid structure, resulting in the direct formation of a gas.
