  1. 2. these materials are very good thermal conductors
  2. 3. an example of a metal that is a very good thermal conductor
  3. 6. the way heat energy passes from particle to particle in a solid
  4. 9. when hot air rises and cold air falls we get a convection .........like the wind
  5. 10. another word for heat
  6. 11. an example of convection is when ....... rises up a chimney
Down
  1. 1. hot air is less ..... than cold air
  2. 3. hot air rises, cold air falls
  3. 4. surfaces that are this are good at reflecting infra red
  4. 5. the opposite of good conductors
  5. 7. when a metal is heated the particles get more energy so .......... faster
  6. 8. no particles therefore no conduction can happen through this
