Substance that is composed of two or more elements or compounds that are not chemically combined is called mixture.
- A material system known as a mixture is composed of two or more separate components that are joined physically but not chemically.
- When two or more substances are physically combined, their identities are maintained, and the mixture takes the shape of solutions, suspensions, or colloids.
- Homogeneous and heterogeneous mixtures are the two basic categories of mixtures.
- Heterogeneous mixtures have varying compositions and qualities throughout, meaning that the mixture's characteristics are not constant.
- A homogenous mixture is one that shares the same characteristics and composition across its mass.
- For example, the elements in the food we eat, the gases in the air we breathe, and the fuel we use in trains are all mixtures.
