Answer 2

Answer:

By dissolving milk in the water we get a colloidal solution, in which the particle size ranges from 1nm to 1000nm.

Explanation:

The colloidal solution is the mixture or the solution that is formed when one substance has insoluble particles suspended in another substance mostly liquids. These suspended particles are referred as colloids.

When milk is mixed with water the solution formed is colloidal in nature as the milk particles suspend freely in the water medium as colloids.

And the particle size range in the colloidal solution is 1nm to 1000nm.
