  1. 1. Matter is made up of:
    • (a) one solid block
    • (b) tiny particles
    • (c) only air
    • (d) nothing
  2. 2. The spreading of one substance's particles through another is called:
    • (a) melting
    • (b) freezing
    • (c) diffusion
    • (d) boiling
  3. 3. Diffusion is fastest in:
    • (a) gases
    • (b) liquids
    • (c) solids
    • (d) metals
  4. 4. Particles are most tightly packed in a:
    • (a) gas
    • (b) liquid
    • (c) vapour
    • (d) solid
  5. 5. Give one piece of evidence that matter is made of particles.
  6. 6. Why is diffusion faster in gases than in liquids?
  7. 7. Describe the arrangement and movement of particles in the three states of matter.

  1. 1. (b) tiny particles — All matter is composed of very tiny particles.
  2. 2. (c) diffusion — This mixing due to particle motion is diffusion.
  3. 3. (a) gases — Gas particles move most freely, so diffusion is fastest in gases.
  4. 4. (d) solid — Solids have closely packed particles in fixed positions.
  5. 5. A few crystals of potassium permanganate colour a large amount of water, showing matter is made of countless tiny particles.
  6. 6. Gas particles are farther apart and move much faster and more freely than liquid particles.
  7. 7. In solids, particles are tightly packed in fixed positions with strong forces of attraction, so solids have a fixed shape and volume and only vibrate in place. In liquids, particles are close together but can slide over one another, giving a fixed volume but no fixed shape. In gases, particles are far apart with very weak forces and move rapidly in all directions, so gases have neither fixed shape nor fixed volume and fill their container.
