  1. What is heat?
    Heat is a form of energy
  2. State the three different ways heat can move
    Conduction

    Convection

    Radiation
  3. What is a conductor? Give an example
    A conductor is a material that allows heat to pass through to eg. copper, aluminium and brass
  4. 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
  5. Explain conduction
    This is the way heat moves through a material without the material moving eg. along a metal spoon
  6. What is convection?
    This is the movement of heat in liquids and gases by flowing currents eg. heating water in a kettle
  7. Define radiation
    This is the movement of heat in rays eg. the sun and the grill
  8. State the temperature water boils at
    1000C
  9. Do bright surfaces reflect or absorb heat?
    Reflect the heat
  10. Do dark surfaces reflect or absorb heat?
    Absorbs the heat
  11. What happens to a solid, liquid or a gas when it is heated?
    It expands
  12. What happens to a solid, liquid or gas when it is cooled?
    It contracts
  13. What is temperature?
    This is a measure of how hot or cold an object is
  14. State the piece of equipment used to measure temperature
    A thermometer
  15. State the SI unit used to measure temperature
    Kelvin (K)

    Degrees Celsius (0C)
  16. Explain the difference between heat and temperature
    Heat is a form of energy whereas temperature is a measure of how hot or cold an object is
  17. State the SI unit used to measure heat
    Joule (J)
  18. Explain latent heat
    Latent heat is the energy needed to change the state of a substances without changing its temperature
