The flashcards below were created by user mshowley on FreezingBlue Flashcards. What would you like to do?


  1. State the three different ways heat can move
    Conduction

    Convection

    Radiation
  2. What is a conductor? Give an example
    A conductor is a material that allows heat to pass through to eg. copper, aluminium and brass
  3. What is an insulator? Give an example
    An insulator is a material that does not allow heat to pass through it eg. a lagging jacket, clothes and fibreglass
  4. Explain conduction
    This is the way heat moves through a material without the material moving eg. along a metal spoon
  5. What is convection?
    This is the movement of heat in liquids and gases by flowing currents eg. heating water
  6. Define radiation
    This is the movement of heat in rays eg. the sun and the grill
  7. State the temperature water boils at
    1000C
  8. If we increase the pressure does the boiling point of water increase or decrease?
    It increases
  9. If we decrease the pressure does the boiling point of water increase or decrease?
    It decreases
  10. Explain latent heat
    Latent heat is the heat taken in or given out when a substance is changing state without changing temperature
