The document discusses the three common states of matter - solids, liquids, and gases - and explains their properties based on the kinetic theory of matter. It states that solids have a fixed shape and volume as their particles vibrate in a fixed position with no spaces between them. Liquids take the shape of their container but have a definite volume, as their particles are arranged in clusters with small intermolecular spaces. Gases occupy the shape of their container and have no definite volume, as their widely-spaced particles move randomly throughout.

1. The Three States of Matter Solids, Liquids & Gases

2. Matter is anything which occupies space and has mass . Three common states of Matter are solid, liquid, and gas . The properties of these states can be explained in terms of the kinetic theory of matter . Introduction

3. Matter’s made up of small particles (atoms or molecules) The particles are in constant motion The Kinetic Theory of Matter

4. Solids Properties of the States of Matter and the Kinetic Theory of Matter Shape Volume Particles are arranged in a fixed pattern hence they have a definite shape. Particles vibrate about their fixed positions, they have no Spaces between the particles.

5. Particles of a Solid Solid

6. Liquids Shape Volume Particles are arranged in the form of clusters, with little intermolecular spaces between them. They do not have a definite shape since they take the shape of the container. Because of little spaces between the particles, the volume of liquids is definite.

7. Particles of a Liquid

8. GASES Shape Volume Particles are spaced wide apart, they occupy the shape of the container Since they move randomly and occupy the shape of the container, they have no definite volume.
