gasinliquid

Gasinliquid is a concise label used to refer to the presence of gas in a liquid, either dissolved at the molecular level or dispersed as gas-filled bubbles. In thermodynamic terms, gas solubility in a liquid is governed by Henry's law: the concentration of dissolved gas is proportional to its partial pressure above the liquid, with temperature affecting the proportionality constant. Most gases become less soluble as temperature rises, though exceptions exist at high pressures or with specific solvents.

Two common modes are dissolution and dispersion. Dissolved gas exists when gas molecules are solvated by liquid

Solubility depends on gas type, solvent, and conditions. For example, carbon dioxide dissolves in water to form

Applications and significance: beverage carbonation relies on dissolving CO2 under pressure; environmental science studies dissolved oxygen

Measurement and data: solubility data are compiled as Henry's constants and Schmidt numbers; techniques include gas
