  • A thermometer works because the liquid in it contracts when heated this is an example of
    Convection
    Radiation
    Conduction
  • What is convection?
    Energy that comes from a source
    Heat transfer through liquids or gasses. Heat rises, cool air falls.
    Heat transfer through direct contact
    Prevents heat transfer
  • Which of the following is the best conductor of heat?
    plastic
    water
    air
    aluminum
  • What are the best insulators? (pick 3)
    Glass
    Rubber
    Copper
    Wood
  • What does convention do?
    None
    It's come's from the sun
    When you touch something
    When the air moves cirrculary
  • The diagram shows an example of:
    Conduction
    Radiation
    Convection
  • What is an insulator?
    a material that allows energy in the form of heat to be transferred.
    a material that prevents heat from being transferred.
    something that creates thermal energy.
  • What is an example of convection?
    Feeling the sunlight on your face
    When the water in the pot circles hot water to the top and cold water falls
    A metal spoon heating up as you stir hot soup
    When you put your hands over a fire to warm them
