Answer 1

Concept:

Colloidal particle:

A colloid is a mixture in which one of the substances is split into very minute particles which are dispersed throughout a second substance.
The substance which is dispersed is called a dispersed phase whereas the one in which the first substance is distributed is called a dispersion medium.
The size of colloid particles generally ranges between, 1 to 1000 nanometres i.e. 10^-5 to 10^-7 cm.

Hence, the size of the colloidal particle is 10-3 - 10-6mm.

1 0^{- 5} - 1 0^{-}

1 0^{- 5} - 1 0^{- 7} cm
