Answer 1

Answer:

1) SOL:-

Sol, in physical chemistry, a colloid (aggregate of very fine particles dispersed in a continuous medium) in which the particles are solid and the dispersion medium is fluid. If the dispersion medium is water, the colloid may be called a hydrosol; and if air, an aerosol.

2) GEL:-

A gel is a semi-solid that can have properties ranging from soft and weak to hard and tough. Gels are defined as a substantially dilute cross-linked system, which exhibits no flow when in the steady-state.

Answer 2

Answer:

$\bold{AnswEr}$

→A gel is a sol in which the solid particles are meshed such that a rigid or semi-rigid mixture results. Examples: Fruit jelly is an example of a gel.

→Cooked and cooled gelatin is another example of a gel.

→ The protein molecules of gelatin crosslink to form a soid mesh which contains pockets of liquid.
