Matter

Matter can be classified according to physical and chemical properties. It occupies space and has mass.

The three states of matter are-

• solid,
• liquid, and
• gas.

A physical change involves the conversion of a substance from one state of matter to another, without changing its chemical composition

Classification of matter on the basis of pure substances and mixtures

Matter can be classified into two categories:

• pure substances and
• mixtures.

1.Pure substance

A pure substance is a form of matter which has a constant composition and properties and remains  constant throughout the sample.

2.Mixtures.

Mixtures are those physical combinations of two or more elements and/or compounds. In this the  identities are retained and mixed in the form of solutions, suspensions and colloids.
