Anything which occupies( fill) space and has mass is called matter. Air and water; hydrogen and oxygen; sugar and sand; silver and steel; copper and coal; iron and wood; ice and alcohol; milk and oil; rocks and minerals; are all different kinds of matter, because all of them occupy space and mass.

[PARA 2]

If we look around us, we can see a large number of things of different shapes, sizes and textures. Many of these things are used by us in our everyday life. For example, we eat food, drink water, breathe in air and wear clothes. We use able and chair for studying and bed for sleeping. We also see other human beings, various animals, plants and trees around us. The things like food, water, air, clothes, table chair, human beings, animals, plants, trees etc. are all examples of matter.

[PARA 3]

The only conditions for ‘something’ to be matter are that it should occupy space and have mass. Now, the things like friendship, love, affection, hatred, good manners, do not occupy space and do not have mass. So, from the point of view of chemistry, things like affection, hatred are not considered matter.

[PARA 4]

Matter can be classified in a number of ways. Ancient Indian philosophers said that all matter, living or non-living was made up of five basic elements: air, earth, fire, sky and water. Modern day scientists classify matter in two ways: on the basis of its physical properties and on the basis of its chemical properties. On the basis of physical properties, matter can be classified as solids, liquids and gases. On the basis of chemical properties, matter is classified as elements, compounds and mixtures.
