space is called matter. Look around you and make a list of objects
that occupy space and have weight.

Matter exists in three states—Solid, liquid and gas.

Sometimes, the same matter can exist in
three di erent states. For example, water

is a liquid normally; when we freeze it,
it becomes solid (ice). e same water,

when boiled for some time, changes into Ice Water Water vapour
