Yes, fog is a colloid. Now if we recall the definition of a colloid “it is any substance in which the tiny insoluble particles are spread over a larger volume of another material.” Fog or a cloud is a type of colloid consisting of a liquid (water) dispersed in a gas (air).
Is fog An example of colloid?
Fog is an aerosol, a type of colloid consisting of a liquid (water) dispersed in a gas (air).
Is fog smoke is a colloid?
-Generally any colloid consisting of a solid dispersed in a gas is called smoke. A liquid dispersed in a gas is referred to as a fog. As we can see fog is an example of a colloid of tiny particles of water vapor and air.
Is fog a colloid or emulsion?
Fog is an aerosol. Aerosols are colloidal solutions in which liquids are dispersed in a gas. In case of fog, tiny particles of water are suspended in the air.
What kind of solution is fog?
Fog is a colloidal solution in which water (liquid, dispersed phase) is dispersed in the air (gas, dispersion medium).
Is fog a substance?
Fog is a visible aerosol consisting of tiny water droplets or ice crystals suspended in the air at or near the Earth’s surface. Fog can be considered a type of low-lying cloud usually resembling stratus, and is heavily influenced by nearby bodies of water, topography, and wind conditions.
Is fog an example of?
Fog is an example of colloidal system with liquid dispersed in gas.
Is fog an example of a solution?
Fog is an example of colloidal solution. As you know that colloidal solution is a heterogeneous mixture and fog is also a heterogeneous mixture.
Is fog a Lyophilic colloid?
Fog is not a lyophilic colloid. Fog is a colloidal solution of liquid in a gas in which liquid is the dispersed phase whereas gas is the dispersion medium. Fog is a colloidal solution of liquid in a gas in which liquid is the dispersed phase whereas gas is the dispersion medium.
Why is fog a solution?
Fog is a colloid since it is a heterogeneous mixture of water, air and suspension particles.
What is this fog?
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.
Is fog mixture of solid and gas?
Some examples of mixtures are:
The liquid in gas mixture: fog, mist, vapor, and hair sprays. Gas in solid mixture: aerogel, Styrofoam. Solid in gas mixture: Smoke, ice clouds, dust.
Is cloud a colloid?
Answer and Explanation: Clouds are an example of a colloid. The water or ice is mixed with the air of the atmosphere but doesn’t bond with the air.
Is air a colloid?
Yes, the air is a colloid since it contains dust particles and water vapour.
Which type of colloidal system is fog?
Fog is an example of an aerosol particle thus cloud or fog is a colloidal system in which the dispersed phase is liquid and dispersion medium is gas. Therefore the correct answer to the question cloud or fog is a colloidal system in which the dispersed phase and dispersed medium are liquid and gas.
What type of colloid is smog?
Smog is a colloidal mixture (aerosol) of liquid and solid particles dispersed in a gas. Explanation: A colloid is a colloidal dispersion of a two-phase heterogeneous mixture made up of a dispersed phase of tiny particles that are distributed evenly within a continuous phase.
Is fog liquid in gas?
According to our question, the correct answer is liquid in gas as Fog is the part of a colloidal system in which liquid is said to be dispersed in gas. Fog is an example of aerosol in which the dispersed phase is liquid and dispersion medium is gas.
What compound is fog?
Chemical composition of fog water was clearly dominated by H+, NH4+, NO3– and SO42–. pHs ranged from 2.27 to 5.95. Sulfur dioxide emissions and nitrogen oxide emissions were the main precursors of fog acidity.
What kind of colloid are cloud and fog?
Colloids of gas with dispersed phase as solids or liquids are called Aerosols. Fog is example of aerosol particle thus cloud or fog is a colloidal system in which the dispersed phase is liquid and the dispersion medium are gas. Thus option B is correct.
Is foggy air heterogeneous mixture?
Gases only form homogeneous mixtures. So, clear air is a homogeneous mixture. But if there is a dispersion of liquid droplets in air (fog) or of solid particulates (smoke), then the resulting mixture of air and the liquid of solid particules is a heterogeneous mixture.
Is fog An example of emulsion?
Fog is an example of colloidal system with liquid dispersed in gas.
Is fog example of gas?
Yes, Fog is an example of a colloidal system with liquid dispersed medium is gas. It is an aerosol of liquid.
Is fog An example of evaporation?
The warm, moist air cools as it mixes with the colder air, allowing condensation and fog to occur. Evaporation fog can be one of the most localised forms of fog. It can happen when: Cold air moves over heated outdoor swimming pools or hot tubs, where steam fog easily forms.
Is blood a colloid?
Blood is a colloid. It has blood cells, nutrients, minerals, etc. which are the dispersed phase, and the dispersing medium is plasma (containing water and other dissolved components).
Is paint a colloid?
Dried paint is typically considered to be a colloid, as the dispersed particles are indefinitely spread throughout the binder (dispersing medium). When paints are manufactured, the pigments are very finely ground, often with the binder, to create a particle size that is colloidal.
Is water a colloid?
Colloids are mixtures in which one or more substances are dispersed as relatively large solid particles or liquid droplets throughout a solid, liquid, or gaseous medium.Selected Answers.

Is fog Lyophilic or Lyophobic?
The gum can be separated from the water and can be remixed, so the gum is a lyophilic colloid. Fog is colloid in which the dispersed phase is liquid water droplet and the dispersion phase is gas. We cannot separate the water droplet from gas and cannot be remixed, so fog is not a lyophilic colloid.
Which is a Lyophilic colloid?
-Lyophilic colloids: Lyophilic colloids are the colloidal solution in which the dispersed phase or the particles have a very strong affinity with the liquid. The solution of this colloid is known as lyophilic sol. These can be easily prepared by direct mixing or heating. The lyophilic sols are reversible in nature.
Which are lyophobic colloids?
The colloidal system in which the dispersed phase have no affinity for the dispersion medium are called lyophobic (solvent hating) colloids. These are irreversible colloids as once peptized they cannot be converted back to colloids.
