4.Name any four properties with one example each, that can be used for sorting materials into groups.
Answers
Explanation:
1.So for the convenience and to make the study of different materials easier and convenient we group the materials on the basis of different properties. The grouping or the classification of materials makes the study easier and also saves our time and energy. Periodic table is a perfect example of this grouping.
2.A saturated solution is a solution that contains the maximum amount of solute that can be dissolved under the condition at which the solution exists. ... This state is when the solution has reached a point in which no more solute can be added.

4.Explanation:
different sizes and shape. for example. big and small etc.
different physical properties. for example. metals and non metals etc.
difference in weight. for example. light and heavy.
difference in chemical properties.
