Question

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Why do we need to separate different components of a mixture? Give two examples.

Answer 1

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> When two or more substances are mixed together they form a mixture. Components of a mixture should be separated because some components may not be useful or may spoil the useful component of the mixture.
Examples:
1)Removal of stone pieces from wheat, rice or pulses by hand
2) Separation of tea leaves from tea with a strainer
