Smog, or smoke fog, is a type of intense air pollution. The word “smog” was coined in the early 20th century, and is a portmanteau of the words smoke and fog to refer to smoky fog due to its opacity, and odor.
What is a smoke fog?
A dense fog (water droplets suspended in the atmosphere) that forms away from a fire site when surface smoke comprised of increased fine particulates and water vapor, combines with ambient air that is already prone to natural fog formation.
What word means smoke and fog?
Smog
Smog is a great example of a portmanteau, a word formed by combining two other words into one: it comes from smoke and fog. Definitions of smog. air pollution by a mixture of smoke and fog. synonyms: smogginess. type of: air pollution.
What causes smoke and fog?
Photochemical smog is produced when sunlight reacts with nitrogen oxides and at least one volatile organic compound (VOC) in the atmosphere. Nitrogen oxides come from car exhaust, coal power plants, and factory emissions. VOCs are released from gasoline, paints, and many cleaning solvents.
Is smoke the same as fog?
Smoke is differentiated from other atmospheric effects in that it is composed of solid particles released during combustion, rather than the liquid droplets that fog or haze are composed of.
How long does smoke fog last?
How long your fog juice will last depends on the wattage of your machine. One quart of fog juice will generally burn for six hours in a 400-watt compact fog machine (four hours in a low lying machine) and a 1,000-watt machine will burn for two hours.
What is fog in simple words?
Fog shows up when water vapor, or water in its gaseous form, condenses. During condensation, molecules of water vapor combine to make tiny liquid water droplets that hang in the air. You can see fog because of these tiny water droplets. Water vapor, a gas, is invisible. Fog happens when it’s very, very humid.

What are the components of smoke and fog?
Smog is made up of many chemicals including nitrogen oxides (NOx), sulphur dioxide (SOx), carbon monoxide (CO), and volatile organic compounds (VOCs), but the two main components of smog are particulate matter (PM) and ground-level ozone (O3).
What is the two differences between fog and smoke?
Thus, smoke and fog differ in terms of dispersion phase. In smoke, dispersion phase is sold and in fog, dispersion phase is a liquid. Note: Smoke is formed when particles of dust get mixed with air. Fog is formed when water vapours condense to form liquid water droplets that hang in air.
Does fog clean the air?
Fog and rain can clean the air effectively. At the same time however, chemicals and compounds that pollute the air can fall with rain to pollute soil and surface waters.

When the cool air mixes with the warm moist air over the water, the moist air cools until its humidity reaches 100% and fog forms. This type of fog takes on the appearance of wisps of smoke rising off the surface of the water.
Does fog have a smell?
Pure fog has no scent. It’s pure water, and is as scentless as it is tasteless. However, the water droplets that form fog can absorb chemicals from the air and deliver concentrated amounts of those impurities directly to your olfactory receptors. So, fog smells like whatever the air has in it…
Is fog smoke toxic?
No. Smoke is made up of solid particles that are a by-product of combustion. Glycol/water fogs are not burned, they are vaporized similar to boiling water. They become pure liquid micro-droplets that leave no residue when evaporated.
