  2. answer 1. Label these states of matter? Solid Liquid Gas

  3. answer 2. Which state of matter has a fixed shape and volume? Solid

  4. answer 3. Which state of matter has a fixed volume but no fixed shape (it takes the shape of the container it’s placed in)? Liquid

  5. answer 4. Which state of matter doesn’t have a fixed volume or shape (it expands to fill the container)? Gas

  6. 5. Explain why cooling the hot ball allows it to fit through the hoop? The ball has contracted. The particles which make it are closer together.

  7. answer 6. What are the small particles called that make up all matter? ATOMS

  8. answer 7. Describe how the particles are arranged in a solid? They vibrate and are arranged in rows with very small spaces between them.

  9. answer 8. Which state of matter has small spaces between the particles but is NOT arranged in neat rows? Liquid

  10. answer 9. What describes particles in a liquid sliding over each other? FLOW

  11. answer Which state of matter has particles which constantly move about and have big spaces between them? GAS

  12. answer 11. Which state of matter has the most energy? Gases have the most energy Solids have the least energy

  13. answer 12. Which state of matter can be compressed? Why? Gases Because they have large spaces between molecules

  14. answer 13. Can solids be compressed? Explain you answer. No Because there are only small spaces between the particles

  15. answer 14. Can liquids be compressed? Explain you answer. No Because there are only small spaces between the particles

  16. 15. What will happen to the total volume when these are mixed? Why? The volume will decrease. The small particles fit into the gaps between the large particles

  17. 16. Explain why heating the ball stops it fitting through the hoop? The ball has expanded. The particles which make it are further apart.

  18. answer 17. What is diffusion? The movement of particles from a region of high concentration to a region of low concentration

  19. 18. Which state of matter diffuses easily? Gases diffuse easily Liquids less quickly Solids DO NOT diffuse easily

  20. answer 19. Which word is used to describe a solid changing into a liquid? Melting

  21. answer 20. What happens at melting point? A solid changes into a liquid

  22. answer 21. Which word is used to describe a liquid changing into a gas? Evaporation

  23. answer 22. What happens at the boiling point of a substance? It changes from a liquid to a gas.

  24. answer 23. Which term is used to describe a substance changing from a liquid to a solid? Freezing

  25. 24. What do you call the temperature at which a substance changes from a liquid to a solid? FREEZING POINT

  26. 25. What will happen to a substance as you heat it? It EXPANDS

  27. 26. What happens when a substance expands? The particles move further apart

  28. 27. Explain why the bimetallic strip bends when heated? The two metals expand at different rates
