The melting of an ice cube is an example of evaporation. Evaporation of acetone which is used for removing nail paint is another everyday example of evaporation. Distillation is the process in which two mixtures are separated with the help of evaporation as boiling of these mixtures is involved.

Evaporation is the process by which water changes from a liquid to a gas or vapor. Evaporation is the primary pathway that water moves from the liquid state back into the water cycle as atmospheric water vapor.

Examples of Sublimation The best example of sublimation is dry ice which is a frozen form of carbon dioxide. When dry ice gets exposed to air, dry ice directly changes its phase from solid-state to gaseous state which is visible as fog. Frozen carbon dioxide in its gaseous state is more stable than in its solid-state.

Evaporation is a phase transition from the liquid phase to the gas phase that occurs at temperatures below the boiling point at a given pressure. Boiling is a phase transition from the liquid phase to the gas phase that occurs at or above the boiling temperature.

Sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state. The reverse process of sublimation is deposition or desublimation, in which a substance passes directly from a gas to a solid phase.

Air itself is an example of a gas-gas solution, where other gases are “dissolved” in nitrogen. But liquids and solids can not be dissolved in gas to form a true solution, instead they form colloids.

Homogeneous solutions

In all solutions, whether gaseous, liquid, or solid, the substance present in the greatest amount is the solvent, and the substance or substances present in lesser amounts are the solute(s)….13.2: Types of Solutions and Solubility.

With the increase in temperature, the solubility of a gaseous solute in solution decreases. If we heat water the dissolved gases will escape. Also, soft drinks are refrigerated as carbon dioxide gas is more soluble in cold soft drinks.

Solvent Examples

• Water.
• Ethanol.
• Methanol.
• Acetone.
• Tetrachloroethylene.
• Toluene.
• Methyl acetate.
• Ethyl acetate.

A solution is a homogeneous mixture of two or more components in which the particle size is smaller than 1 nm. Common examples of solutions are the sugar in water and salt in water solutions, soda water, etc. In a solution, all the components appear as a single phase.
