Question

Is Fog A Colloid Or Solution?

Answer 1

A colloid is a combination in which one component is suspended in another by microscopically distributed insoluble particles. Some definitions, however, stipulate that the particles must be dispersed in a liquid, while others broaden the concept to include aerosols and gels.

Complete answer:
The phrase colloidal suspension clearly refers to the entire combination (although a narrower sense of the word suspension is distinguished from colloids by larger particle size). A colloid has a continuous phase and a dispersed phase (suspended particles) (the medium of suspension). The scattered phase particles are around 1 nanometre to 1 micrometre in diameter. The Tyndall effect, which is the scattering of light by particles in a colloid, causes some colloids to appear transparent. Other colloids may be transparent or have a colour. Fog is a visible aerosol made up of small water droplets or ice crystals floating in the air near or at the surface of the Earth. Fog is a low-lying cloud that looks a lot like stratus and is highly impacted by adjacent bodies of water, terrain, and wind conditions. Fog has impacted a variety of human activities, including shipping, travel, and warfare. When water vapour, or water in its gaseous state, condenses, fog forms. Water vapour molecules mix during condensation to form small liquid water droplets that float in the air. Sea fog is created when water vapour condenses around salt particles near bodies of saline water.

Note:
When water vapour condenses into small water droplets floating in the air, fog is formed. Wind convergence into upward motion areas; precipitation or virga falling from above; daytime heating evaporating water from the surface of oceans, water bodies, or wet land; transpiration from plants; cool or dry air moving over warmer water; and lifting air over mountains are some examples of how water vapour is added to the air. In order to produce clouds, water vapour condenses on condensation nuclei such as dust, ice, and salt.
