Science - Matter

  1. What is matter?
    Matter is anything that takes up space and has mass
  2. List the three types of matter
    Solids

    Liquids

    Gases
  3. State a property of solids
    Have a fixed mass

    Have a fixed shape

    Have a fixed volume

    Cannot be easily compressed

    Particles cannot flow
  4. State a property of liquids
    Have a fixed mass

    Have no fixed shape

    Have a fixed volume

    Cannot be easily compressed

    Particles can flow
  5. State a property of gases
    Has a fixed mass

    Has no fixed volume

    Has no fixed shape

    Particles can flow

    It can be easily compressed
  6. What is melting?
    This is when a solid changes into a liquid
  7. What is meant by the melting point?
    This is the temperature a substance melts at
  8. State the melting point of ice
    00C
  9. Explain evaporation
    This is changing a liquid into a gas
  10. What is meant by the boiling point?
    This is the temperature at which a liquid changes to a gas
  11. State the boiling point of water
    1000C
  12. Explain condensation
    This is changing a gas into a liquid
  13. Explain freezing
    This is changing a liquid into a solid
  14. State the freezing point of water
    00C
  15. Explain sublimation
    This is when a substance is heated and they do not melt but turn straight into a gas

    They do not form a liquid
  16. What is a physical change?
    This is when matter changes shape or state but no new substance is formed eg. melting and boiling

    It is easy to reverse (change back)

    There is no change in mass
  17. What is a chemical change?
    This is when a new substance is formed eg. rusting

    It is not easy to reverse (change back)

    There is no change in mass
  18. State the Law of Conservation of Mass
    The Law of Conservation of Mass states that matter cannot be created or destroyed but can change from one form to another
