  1. what are the three way heat can be transferred?
    radiation conduction and convection
  2. what surface is best for absorbing heat?
    black matt
  3. what are the three states of matter and describe the formation?
    solid,organised formation liquid,simarlar formation to solid but got some room to pass each other. gases,irregular formation and are free to move around
  4. what is convection?
    convection is where particle move towards a heat source

    then they heat up and start to rise

    as it moves away from the heat source it cool and start to sink
  5. what is condensation ?
