Is milk heterogeneous or homogeneous?

Understand the Problem

The question is asking whether milk has a uniform composition throughout (homogeneous) or if it contains distinct, separate phases (heterogeneous). This relates to the understanding of the physical properties of mixtures.

More Information

Milk is considered a homogeneous mixture because it is uniform in composition and appearance—they do not separate out over time. However, untreated or raw milk can be considered heterogeneous because it might separate into different components.
