Answer 2

Sol

• A sol is a colloid made out of very small particles in a continuous liquid medium. Sols are stable and show the Tyndall effect.
• Sol is the liquid state of a colloid solution.
• The sol can be converted to gel by cooling.  
• Dehydration of sol is relatively very easy.  
• Sol has a low viscosity.    
• Sol is usually classified further to lyophobic and lyophilic.
• The sol does not possess a definite structure.
• The dispersion medium of the sol may be water (hydrosol) or alcohol (alcohol).  
• Blood, pigmented ink, cell fluids, paint, milk of magnesium and mud.

Colloid/Gel

• A gel is a complex fluid consisting of two or more phases typically composed of a solid dispersed in a liquid.
• Gel can be described as solid or semi-solid (jelly-like) stage of a colloidal solution.
• The gel can be converted to sol by heating.
• Dehydration of gel is not possible.  
• The gel has a high viscosity.
• Gel does not have a further classification.
• The gel has a honeycomb-like structure.  
• The dispersion medium of the gel will be hydrated colloid particles.
• Fruit jelly, cooked gelatin jelly, fog, mist, ice cloud, hair sprays.
