    Radiation and Conduction
  • What is a heat conductors?
    something that blocks energy from flowing through.
    a material that allows energy in the form of heat to be transferred.
    something that creates thermal energy.
  • What is radiation?
    Energy that comes from a source and travels through space. (no contact)
    Prevents heat transfer
    Heat transfer through direct contact
    Heat transfer through liquids or gasses
  • The diagram shows an example of:
    Convection
    Radiation
    Conduction
  • When a fan spins, what heat transfer is it?
    Conduction
    Radiation
    Have no idea
    Convection
  • What are examples of radiation? (pick 2)
    Feeling the sunlight on your face
    A metal spoon heating up as you stir hot soup
    When you put your hands over a fire to warm them
    The pan heating up on the stove
  • Through what can radiation be transferred?
    Liquid
    None
    Gas
    Solid
  • True or False higher temperature means faster moving molecules
    False
    True
  • What is conduction?
    Energy that comes from a source
    Prevents heat transfer
    Heat transfer through liquids or gasses
    Heat transfer through direct contact.
  • What is convection?
    Heat transfer through direct contact
    Energy that comes from a source
    Heat transfer through liquids or gasses. Heat rises, cool air falls.
    Prevents heat transfer
  • Heat transfer by radiation
    is not possible from human beings to their environment.
    none of the above.
    does not require any material between the radiator.
    does not occur from light bulbs ( they are too bright.
  • What state of matter does convention take place in?
    Solids
    Only gas
    Liquids & Gas
    Only liquids
  • Which heat transfer has electromagnetic waves?
    Conduction
    Convection & Conduction
    Radiation
    Convection
  • Which color of visible light has the shortest wavelength?
    Yellow
    Red
    Violet
    Blue
  • What does convention do?
    When you touch something
    It's come's from the sun
    None
    When the air moves cirrculary
  • What is an example radiation?
    Feeling heat from the sun
    Touching the hot stove
    Radiation is not a heat transfer
  • What are the best conductors? (pick 3)
    Glass
    Water
    Copper
    metal
  • What is conduction?
    It when the air circulates
    Conduction is when you touch
    Conduction is when you absorb waves

  • What is an example of convection?
    A metal spoon heating up as you stir hot soup
    Feeling the sunlight on your face
    When you put your hands over a fire to warm them
    When the water in the pot circles hot water to the top and cold water falls

    Spread out
    Touching
    Somewhat close together
    Realy spread out
