What is meant by separation of substances?

Separation of substances is the process of removing unwanted or different components from a mixture to obtain useful or pure materials. In everyday life, most materials are found mixed together, so separating them helps us use them effectively.

For example, when you remove stones from rice before cooking, you are separating unwanted substances. Similarly, extracting salt from seawater or filtering tea leaves from tea are also common separation processes.

This concept is important in both daily life and industries, where different techniques are used based on the type of mixture and the properties of its components, such as size, weight, or solubility.
