What is matter in simple terms? Introduction. |
Matter makes up all the things in the universe. It occupies space and has mass. Matter is made up of tiny particles called atoms. Usually an atom does not exist independently. Therefore, atoms combine to form molecules. The atoms / molecules are tightly packed in solids and loosely packed in liquids and gases. These particles have random motion in gases. |

What is the Kinetic Molecular Theory? |
The theory that enables us to understand the behaviour of molecules in solids, liquids and gases is called the Kinetic Molecular Theory. |

What is the Composition Of Matter? |
• Matter is composed of molecules. • The molecules of a given substance are identical in all respects. • For example, all the molecules of water are identical in terms of their chemical properties. |
