Question

How is fog different from smoke?

Answer 1

Hint: A suspension of small solid particles or liquid droplets in air or another gas is known as an aerosol. Fog or mist, dust, woodland exudates, and geyser steam are examples of natural aerosols. Particulate air pollution and smoke are examples of anthropogenic aerosols.

Complete answer:
When a substance undergoes combustion or pyrolysis, smoke is formed from a mixture of airborne particles and gases, as well as the amount of air entrained or otherwise incorporated into the mass. It's a frequent by-product of flames (such as stoves, candles, internal combustion engines, oil lamps, and fireplaces), but it may also be utilised for pest management (fumigation), communication (smoke signals), military defensive and offensive capabilities (smoke screen), cooking, or smoking (tobacco, cannabis, etc.).
Fog is a visible aerosol made up of microscopic water droplets or ice crystals hanging 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 greatly impacted by neighbouring bodies of water, geography, 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.
Smoke is a collection of airborne solid particles distributed in a dispersion medium, such as a gas. Smoke particles are a mist or aerosol of solid particles with a size distribution that is near to optimal for scattering visible light. Fog is a collection of liquid droplets or ice crystals floating as gas near the Earth's surface in the dispersion phase. Water vapour molecules unite during condensation to form small liquid water droplets that float in the air. Sea fog is generated when water vapour condenses around salt particles near bodies of saline water.

Note:
When water vapour condenses into small water droplets hanging 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.
