Detailed explanation-1: -A heterogeneous mixture consists of two or more phases. When oil and water are combined, they do not mix evenly, but instead form two separate layers. Each of the layers is called a phase. In the case of vegetable soup, one phase would be the liquid soup itself.

Detailed explanation-2: -The statement that is true is heterogenous mixture are not pure substances. Explanation: A heterogenous mixture can simple be defined as a mixture that is not made up of uniform particles. As a heterogenous mixture is made up of different kinds of atoms, hence it is not a pure substance.

Detailed explanation-3: -A heterogeneous mixture contains two or more ingredients or phases. The phases might be at least two solids, liquids, or gases, or a solid/liquid (suspension), liquid/liquid (emulsion), gas/liquid (aerosol), or gas/solid (smoke). The different phases mix together, but are physically separate.

Detailed explanation-4: -There are always two or more phases in a heterogeneous mixture, where you can identify a region with properties that are distinct from those of another region, even if they are the same state of matter (e.g., liquid, solid).

Detailed explanation-5: -Detailed Solution. The correct answer is Uniform composition.
