  • Sean was studying upstairs in his room when he began to smell food being cooked in the kitchen downstairs....What explains this?
    Diffusion
  • Have a definite volume and do not flow?
    Solid
  • List the 3 common states of matter
    Solid, Liquid and Gas
  • Describe what happens to the particles in a liquid when it is heated?
    The particles get more energy and move faster and faster, eventually breaking away from the liquid state and forming a gas
  • Explain condensation
    Is the changing of a gas to a liquid - when a gas is cooled the particles slow down and liquid is formed.
  • Have a definite shape?
    Solid
  • Do not have a definite shape or volume?
    Gas
  • Define evaporation
    Is the changing of a liquid to a gas at the surface of a liquid
  • The particles are in fixed positions and do not move but CAN vibrate?
    Solid
  • The particles are packed closely together?
    Solid
  • What state? - The particles are farther apart than in other states, and are only very weak forces present
    Gas
  • Define freezing point
    Is the temperature at which a liquid changes to a solid
  • What is the state ? The particles have more freedom of movement than of that in a solid
    Liquid
  • Define matter
    Is anything that takes up space and has mass
  • Can be compressed easily
    Gas
  • Define melting point
    the temperature at which a solid changes to a liquid
  • How do I measure the boiling point of water?
    Using a thermometer
  • Outline the arrangement of the states of matter in order of decreasing freedom of movement of their particles
    Gases, Liquids, Solids
  • Liquids have a definite ______________ and can flow?
    Volume
  • What state? Particles can slide over each other, not as fixed as another state of matter
    Liquid
  • What is the boiling point of a liquid?
    The temperature at which a liquid changes to a gas throughout the liquid
