between the substances. Examples of mixtures are air (a mixture of different gases) and cereal in milk. • The main characteristics of mixtures are that the substances that make them up are not in a fixed ratio‚ these substances keep their physical properties and these substances can be separated from each other using mechanical means. • A heterogeneous mixture is one that consists of two or more substances. It is non-uniform and the different components of the mixture can be seen
