Pure substances exhibit characteristic properties such as specific melting and boiling points, density, solubility, and chemical reactivity. These properties remain consistent regardless of the sample's size or source, distinguishing pure substances from mixtures.

Soft drinks and soil differ from pure substances in that they are mixtures composed of multiple pure substances. Soft drinks contain water, sugar, flavorings, and carbon dioxide, while soil consists of minerals, organic matter, water, and air. Their compositions vary, unlike pure substances.

Dissolved sodium chloride can be separated from water through the physical process of evaporation. By heating the solution, the water evaporates, leaving behind the solid sodium chloride, which can then be collected separately.

Common examples of mixtures found in everyday life include air (a mixture of gases), sea water (a mixture of water and dissolved salts), salad (a mixture of vegetables), soup (a mixture of various ingredients), and coffee (a mixture of water, coffee grounds, and possibly sugar and milk).

An example of a pure substance is elemental gold (Au). It consists solely of gold atoms and maintains a consistent composition throughout, displaying characteristic properties such as specific melting and boiling points.

Milk is considered a mixture rather than a pure substance because it contains various components such as water, fat, proteins, and minerals. These components maintain their individual properties within the mixture, making milk heterogeneous rather than homogeneous.

A scientist defines a pure substance as one consisting of a single type of particle, where all constituent particles are identical in their chemical nature. Pure substances exhibit uniform properties and cannot be separated into simpler substances by physical means.

In science, "pure" typically refers to substances or systems that are free from contamination or extraneous elements, allowing for precise study and analysis. It denotes a state of homogeneity and absence of impurities, enhancing experimental reliability and accuracy.

During evaporation, water molecules absorb energy from their surroundings, gaining kinetic energy. This increased energy causes the molecules to break free from the liquid phase and enter the gaseous phase, forming water vapor.
