Anjali knows that whole milk has more fat than skim milk. However, the solid fat doesn’t seem to separate from the liquid milk even after it has been in the fridge for a few days. This is evidence that milk is a;  COLLOID

The first case is an illustration of a suspension, and the second case of a milk is an example of a colloid.

Explanation:

In the field of chemistry, a heterogeneous mixture comprising the solute particles that do not get dissolve, however, get suspended all through the majority of the solvent, and floats freely around in the medium is known as a suspension.  

On the other hand, a homogenous non-crystalline component comprising ultramicroscopic particles or bigger molecules of one material getting dispersed via a second material is known as a colloid. The colloids comprise emulsions, gels, and sols.
