What is a mixture?

The video explains mixtures, which are combinations of different materials that do not chemically react to form new substances. It covers various types of mixtures, such as gases, liquids, and solids, and provides examples like air, salad, and mud. The video also discusses how mixtures can be separated back into their original components unless a chemical reaction occurs, forming a new substance, as seen in marmalade and baking a cake. These changes are irreversible.
