Question

What is matter. Write three states of water in which it exists.

Answer 1

Matter refers to anything that occupies space and has mass.

The three states of water in which it can exist are:

(i) Solid state- It refers to a state in which particles are tightly packed and it has a fixed shape and volume. For example- ice.

(ii) Liquid state- It refers to a state in which particles are loosely packed and it has a fixed volume but not a fixed shape. For example- water.

(iii) Gaseous state- It refers to a state in which particles are very loosely packed and it has no fixed shape and volume. For example- water vapors.

Thus, water exists in the form of ice, water and water vapor.
