Other questions in this quiz

2. What will the experiment show?

  • Both air and bromine particles are moving randomly and there re large gaps between the particles: therefore, they can easily mix together
  • They are very fast

3. What is crystallisation?

  • The separation of a dissolved solid from a solution, when the solid is much more soluble in hot solvent than in cold
  • Melting a compound before we can electrolyse it

4. What is diffusion?

  • When a gas moves freely from an area of high concentration to low concentration
  • When a gas gives of a smell

5. How can we use diffusion to investigate particles?

  • Wait, for five minutes, for the bromine gas to diffuse from its flask to the other
  • Release bromine gas into the atmosphere
