  1. 7G Particle model of solids, liquids and gases 7G Particle model of solids, liquids and gases What is the world made of? Solids, liquids and gases The particle model

  2. 7G Particle model of solids, liquids and gases What is the world made of?

  3. 7G Particle model of solids, liquids and gases Solids, liquids and gases

  4. 7G Solids, liquids and gases - It’s a matter of fact! Matter is all the stuff around you – everything you can touch, see or smell. Everything in the Universe is made of matter. There are 3 states of matter…

  5. 7G Solids, liquids and gases - It’s a matter of fact!

  6. Classify the following substances as a solid, a liquid, or gas :- Petrol - oxygen - cooking oil - Wood - iron - water - Air - Milk - Nitrogen - Pencil - Glass

  7. 7G Solids, liquids and gases - In a state! Fill in the table with the answers to these testing questions: Does it have a fixed shape? Does it have a fixed volume?

  8. 7G Solids, liquids and gases - In a state! Now answer some more testing questions about a solid, a liquid and a gas.

  9. 7G Particle model of solids, liquids and gases The particle model

  10. 7G The particle model – Solids, liquids and gases Theparticle modelof matter describes: how particles are arranged how much energy particles have and how they move In some matter the particles are held together by forces of attraction. Use the particle model to decide if the forces of attraction are strong, weak or do not exist.

  11. 7G The particle model – Solids, liquids and gases The particle model of a solid

  12. 7G The particle model – Solids, liquids and gases The particle model of a liquid

  13. 7G The particle model – Solids, liquids and gases The particle model of a gas

  14. 7G The particle model – Solids, liquids and gases solid particles… - are very close together in a fixed arrangement - have a small amount of energy - vibrate but do not move liquid particles… - are close together but have no fixed arrangement - more energy than solid particles - vibrate and can move about gas particles - are far apart and have no fixed arrangement - have a large amount of energy - move rapidly in all directions

  15. 7G The particle model – Changing state Water can be a solid, liquid or a gas. Its state depends on how much energy the water particles have. water steam ice If enough energy is added to or removed from the particles a change of state can occur.

  16. 7G The particle model – Changing state water steam ice Match the change of state to the correct arrow on the diagram. freezing condensing melting evaporating What happens to the particles during each change of state? CLUE: Think about their energy, their movement and the distance between them.

  17. 7G The particle model – True or false? True or False? 1. The particles in gas have a large amount of energy. 2. The particles in a solid have no forces of attraction between them. 3. The particles in a liquid are close together and have a fixed arrangement. 4. When a liquid freezes it becomes a gas. 5. Evaporation describes the change from a liquid to a gas. 6. When a liquid loses energy it becomes a gas. 7. A gas condenses to a liquid when its particles lose energy. 8. When the particles in a solid gain energy the solid melts. TRUE FALSE FALSE FALSE TRUE FALSE TRUE TRUE
