Key Concepts

Sublimation

Sublimation is the direct change of a substance from a solid state to a gaseous state without passing through an intermediate liquid phase. This process happens under specific pressure and temperature conditions that allow the particles to directly transition to a gas.

Deposition

Deposition is the reverse of sublimation, where a substance transitions directly from the gaseous state to the solid state without first becoming liquid. This process occurs when the gas particles lose enough energy to form a solid structure directly.

Freezing

Freezing is the transition from a liquid to a solid state. In this process, a substance releases thermal energy, causing its particles to lose mobility and arrange themselves into a fixed, orderly structure characteristic of a solid.

Melting

Melting is the phase transition from a solid to a liquid state. This process occurs when a substance absorbs thermal energy, allowing its particles to overcome the rigid structure of the solid and move more freely as a liquid.

Phase Transitions

Phase transitions refer to the process of a substance changing from one state or phase (solid, liquid, gas) to another. These changes occur due to variations in temperature or pressure, which affect the movement and energy of the particles within the substance.
