Detailed explanation-1: -A phase is any part of a sample that has a uniform composition and properties. By definition, a pure substance or a homogeneous mixture consists of a single phase. 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.

Detailed explanation-2: -Mixtures: Homogeneous and Heterogeneous A homogeneous mixture, also called a solution, exhibits a uniform composition and appears visually the same throughout. An example of a solution is a sports drink, consisting of water, sugar, coloring, flavoring, and electrolytes mixed together uniformly.

Detailed explanation-3: -Pure Substances. Matter that always has exactly the same composition is classified as a pure substance. Every sample of a given substance has the same properties because a substance has a fixed, uniform composition.

Detailed explanation-4: -A solution is a mixture that is the same or uniform throughout. Think of the example of salt water. This is also called a “homogenous mixture.” A mixture that is not a solution is not uniform throughout.

Detailed explanation-5: -Homogeneous mixture is the mixture in which the composition is uniform and every part of the mixture has the same properties. For example: a mixture of common salt and water is uniform and has the same properties throughout.
