Answer 1

☁️ Your Answer:

• Liquid and Gas (Option C)$.$

✒ Here, the dispersed phase is liquid which is dissolved in gas which is the dispersion medium.

☁️ Explanation:

Depending upon the dispersed phase and dispersion medium, the colloid are divided in many types like Sols, Gel, Emulsion etc.

✒ Dispersed Phase:

• The component which is present in small proportion and consists of particles of colloids dimension.

✒ Dispersion Medium:

• It is the component which is present in excess and acts as a medium in which colloids particles are dispersed.

⬇️ Here, in case of cloud, the liquid particles are dispersion in gas medium. It means small droplets of water are dispersed in the gas in the atmosphere. Hence, Cloud is a Aerosol. More examples of Aerosol are Mist, Fog, Insecticide Sprays etc.

✒ Depending upon the dispersion medium, there are different types of sold which are:

• Water - Aqua/Hydrosol
• Alcohol- Alcosol
• Benzene- Benzosol
• Gases- Aerosol

✒ Some properties of colloids includes:

• They are heterogeneous but appears homogenous.
• The particles are very small and can't be seen with naked eyes.
• They don't settle down when left undisturbed.
• They can pass through filter paper. They can be separated by centrifugation.
• Particles in a colloidal solution follow brownish movement (zig-zag)
• They scatter light.(Tyndall effect)
