6. Heat is measured in joules

  • True
  • False

7. Heat travel in a solid is called conduction?

  • True
  • False

8. What does temperature describe?

  • How hot something is
  • How much energy there is

9. Conduction happens best in solids as the particles are close together

  • True
  • False

10. Does heat always move from a hot object to a cold?

  • Yes until they both become the same temperature.
  • No

11. When the heated solid cools down does it get smaller?

  • Yes (contracts)
  • No

12. Heat transfer in a liquid is called convection

  • True
  • False

13. Are metals good conductors of heat?

  • Yes
  • No

14. When a solid expands it has the same mass but does its density increase?

  • No it actually decreases
  • Yes

15. This is called a convection current

  • True
  • False

16. Can we measure temperature with a thermometer?

  • Yes
  • No

17. When a solid is heated does it gain energy?

  • Yes
  • No

18. Does The extra vibrations in a solid cause the particles to move around

  • Yes- so the solid expands (gets bigger)
  • No

19. Gases are the worst conductors because the. Particles are far apart

  • True
  • False

20. The amount of heat depends on

  • It's temperature, it's material, it's mass
  • How it looks like
  • How big the object is
