Answer:
1.Colloid is a mixture is two or more substances mixed together but not chemically combined ( they can be separated ). They are a special type of mixture where tiny particles of one substance are scattered through another substance.Butter is also a colloid as there are water molecules trapped in between the fat.
2.Tyndall effect, also called Tyndall phenomenon, scattering of a beam of light by a medium containing small suspended particles—e.g., smoke or dust in a room, which makes visible a light beam entering a window.
3.The difference between a solution and a suspension is in the particle sizes involved. A solution is a mixture of ions or molecules (very, very small). Solutions are transparent, meaning that you can see through them. A suspension has bigger particle sizes and so it may look cloudy or murky.
