Why are the properties of mixtures different from those of pure substances?

A pure substance is a substance that cannot be separated into any other kind of substance using a physical or chemical process. All the particles that make up a pure substance have the same color, taste, composition and texture. In other words, it can be an element or compound that consists of only one component with a specific composition, chemical and physical properties.
A mixture is a combination of two or more substances that are not combined using a chemical procedure. The ingredients that make up the mixture do not exist in fixed proportions, and most of the natural substances that you are familiar with are mixtures. Examples of mixtures are water, alcohol, oil, and dye.
