What is difference between fog and smoke?
Sarah Scott general
Fog is water vapor in atmosphere which condenses due to low temperature and forms dense white thing in atmosphere,it is not a pollutant but it reduces visibility. Smoke is a collection of airborne solid and liquid particulates and gases emitted when a material undergoes combustion.
.
Just so, how is fog different from smoke?
Fog: Droplets of water vapour suspended in the air near the ground. An atmosphere in which visibility is reduced because of a cloud of some substance. Smoke: A hot vapour containing fine particles of carbon being produced by combustion. A cloud of fine particles suspended in a gas.
Also, what is made up of smoke and fog? Smog is a type of intense air pollution. The word "smog" was coined in the early 20th century, and is a contraction (portmanteau) of the words smoke and fog to refer to smoky fog; its opacity, and odor. Summer smog is primarily associated with the photochemical formation of ozone.
People also ask, what is the difference between fog and smoke Class 9?
Answer: In smoke and fog. In smoke, solid carbon particles are dispersed in air while in fog, liquid water particles are dispersed in air.
How do you identify fog and smog?
Unlike fog, you can actually smell the smog and know the difference! While fog is whiter in colour, the air we see around us has tones of grey, which the scientists term as smog and not fog. While fog eventually dips down, smog persists in the air and transfers smoke-like particles which we end up ingesting.

Why is Delhi so foggy?
Delhi's winter is marked by very dense fog and haze, which dramatically reduce visibility and makes days colder by cutting off sunlight.Is fog a pollution?
Mist and fog are caused by water droplets in the air, and the only difference is how far you can see. Haze is the reflection of sunlight off air pollution, while smog is what happens when pollution causes low-lying ozone. Mist and fog both occur when there are water droplets in the air.How is fog formed?
Fog forms when the difference between air temperature and dew point is less than 2.5 °C (4.5 °F). Fog begins to form when water vapor condenses into tiny liquid water droplets that are suspended in the air.Does fog help air quality?
Physical activities in the fog and hazeThe fog and haze can increase the air humidity and decrease the oxygen level.Is smog fog?
Smog is a form of air pollution, resulting from chemical toxins dispersed into the atmosphere whereas fog is the accumulation of floating water droplets in the air.Is fog harmful for health?
According to health experts, fog by itself cannot affect health of a person but it is the pollutants entangled in fog which are the root cause of asthma and other respiratory diseases.What does mist look like?
Mist makes a light beam visible from the side via refraction and scattering on the suspended water droplets. "Scotch mist" is a light steady drizzle. Mist usually occurs near the shores and is often associated with fog. Mist can be as high as mountain tops when extreme temperatures are low.Why is fog dangerous?
Fog creates dangerous driving conditions and has been the cause of a high number of accidents and fatalities. Fog is a cloud form at the surface of the earth made of tiny water droplets suspended in the air. The greatest problem with fog is visibility. Slow down and do not drive faster than your vision.What is dispersed phase?
Dispersed phase is the phase that is composed of particles that are distributed through another phase. The main difference between dispersed phase and dispersed medium is that dispersed phase is a discontinuous phase whereas dispersion medium is a continuous phase. Dispersed phase is one of the two phases in a colloid.What is smog Class 9?
cbse-class-9-science. LokeshCBSE March 20, 2018, 3:27pm #1. What is smog? Answer: The suspended particles like unburnt carbon particles and hydrocarbons mix with smoke and fog in the atmosphere, especially in the cold weather to form smog which results in a lowered visibility.What are smoke atoms?
Smoke is made up small particles, gases and water vapor. Water vapor makes up the majority of smoke. The remainder includes carbon monoxide, carbon dioxide, nitrogen oxide, irritant volatile organic compounds, air toxics and very small particles.What is smog explain?
Smog. Smog is a kind of air pollution, originally named for the mixture of smoke and fog in the air. Classic smog results from large amounts of coal burning in an area and is caused by a mixture of smoke and sulfur dioxide. In the 1950s a new type of smog, known as Photochemical Smog, was first described.How do Sol and gel differ from each other give one example for each?
A sol is a type of colloid in which solid is the dispersed phase and liquid is the dispersion medium. Examples include milk of magnesia, mud etc. A gel is a type of colloid in liquid is the dispersed phase and solid is the dispersed medium. Examples include jelly, cheese etc.What is the difference between smog and fog give two examples effects of smog?
Smog is a type of air pollution; the word "smog" is a combination of fog and smoke. Smog is also caused by large amounts of coal burning in an area caused by a mixture of smoke and sulfur dioxide. Fog is a collection of water droplets or ice crystals suspended in the air at or near the Earth 's surface.Are smoke machines safe?
As long as your fog machine is used properly it is perfectly safe to breathe. Most fog machine fluids are made from a water and glycol solution that is not considered to be hazardous, however it may cause respiratory or throat irritation problems in some people.What do smoke machines use?
Heated fog machines use either an inert gas or an electric pump to propel mineral oil, propylene glycol, or glycerin and water mixture into a heat exchanger, where the solution is vaporized. Propylene glycol is used rather than ethylene glycol (ie antifreeze), as the latter is toxic.What does AQI mean?
