Heterogeneous and homogeneous refer to mixtures of materials in chemistry. The difference between heterogeneous and homogeneous mixtures is the degree at which the materials are mixed together.

A homogeneous mixture is a mixture where the components that make up the mixture are uniformly distributed throughout the mixture.

Homogeneous mixtures: air, blood, saturated sugar water

A heterogeneous mixture is a mixture where the components of the mixture are not uniform or have localized regions with different properties.

Heterogeneous mixtures: rocks, oil and water, soup, pizza
