A colloid is a form of suspension in a liquid or gas, the two phases are distinct.
Unlike in a suspension, the particles in a colloid do not separate into two phases on standing.
There are three common phases of matter: solid, liquid, and gas. Additional phases can include plasma and Bose-Einstein condensate.
Halwa is considered a colloid because it is a mixture of two phases - a solid dispersed in a liquid. The sugar, ghee, and other solid ingredients are finely dispersed in water to form a gel-like consistency, creating a colloid.
The two phases of a colloid are the dispersed phase (the particles that are distributed throughout the dispersion medium) and the dispersion medium (the substance in which the dispersed phase is suspended).
A solution has only one phase.A suspension has two phases.A colloid has two phases but the colloidal particles have dimensions under 1 micrometre.

This depends: an ink may be a true sollution or a colloidal solution, or a suspension.

Homogeneous solutions have only one phase.A suspension or a colloid has two phases.
A colloid is a mixture of tiny particles of pure substances that disperse into a substance and do not settle over time. This means that a marshmallow's tiny particles of pure substance do not settle, they stay in their solid form (A fluffy delicious cylendar of mushy yum.)
1) A colloidal system consists of two separate phases: a dispersed phase (or internal phase) and a continuous phase (or dispersion medium) in which the colloid is dispersed.2) A colloid is a substance microscopically dispersed evenly throughout another substance.
