  1. Particle Model of solids, liquids and gases W Richards The Weald School

  2. The Three States of Matter Matter can be in one of three “states”. The three states of matter are SOLIDS, LIQUIDS and GASES. What are their properties? Very difficult to squash, can’t be poured, can’t change shape Difficult to squash, can be poured, can change shape Easy to squash, can be poured, can change shape

  3. Particle theory Particle theory is all about explaining the properties of solids, liquids and gases by looking at what the particles do. View animation SOLIDS In a solid the particles ______ around a _____ position. There is a ______ force of attraction between each particle and they are very _____ together Words – strong, close, vibrate, fixed

  4. LIQUIDS In a liquid the particles are _____ together but can move in any direction. They won’t keep a _____ shape like _____ do. GASES In a gas the particles are very far apart and move _____ in all directions. They often ______ with each other and because they are far apart they can be easily _______. Words – fixed, collide, quickly, close, very, solids

  5. Heating a solid When a solid is heated it expands. We can use particle theory to explain why: View animation

  6. Diffusion The “scent particles” from this hamburger are in high concentration here: Eventually they will “diffuse” out into this area of low concentration: Diffusion is when something travels from an area of high concentration to an area of low concentration. For example, consider the scent from a hamburger… View hamburger animation View diffusion animation

  7. Gas pressure Gas pressure is due to the effect of lots of particles colliding with the side of a container. View gas pressure animation In this experiment the bottle was crushed because there were more collisions on the outside of the bottle than on the inside, so the outside was “pushed in”.
