NCERT Solutions for Class 6 Science Chapter 3 - Q1.
Q1. Why do we need to separate different components of a mixture? Give two examples.
Ans. 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.
E.g.
(a) Tea leaves are separated from the liquid with a strainer while preparing tea.
(b) Removal of stone pieces from wheat, rice or pulses by hand before eating.
