Question

What is formed by the physical combination of two or more substances, which retain their identities? Give an example of such substance.

Answer 1

A mixture is defined as a physical combination of two or more substances that retain their identities.

For example, lemonade is a mixture that has a uniform composition, such as colour and taste of its constituents throughout it. The components - lemon juice and water, though mixed with each other well, retain their individual properties.
