Concept explainers
(a)
Interpretation:
Hot tea has to be classified as a pure substance or a mixture.
Concept Introduction:
Matter can be classified into two type’s namely pure substance and mixture.
Pure substance: A single component that has a constant composition, irrespective of the
Example: Water, sugar etc.
Mixture: A mixture consists of more than one substance and the composition of a mixture is dependent on the sample. The separation of mixture into its components can be done by physical changes.
