What types of mixture are cream and butter?

* Cream: Cream is a mixture of fat globules dispersed in water. The fat globules are not uniformly distributed, and they can be separated using techniques like skimming.

* Butter: Butter is primarily made up of fat, but it also contains water and milk solids. The fat molecules are clustered together, forming a distinct solid phase, while the water and milk solids form a separate liquid phase. This distinct separation makes it heterogeneous.

In contrast, a homogeneous mixture has a uniform composition throughout. For example, saltwater is a homogeneous mixture, where the salt molecules are evenly distributed in the water.
