Across
  1. 3. the transfer of thermal energy from a warmer object to a cooler object.
  2. 6. the highest point on a transverse wave
  3. 8. waves bending around an object.
  4. 9. the transfer of thermal energy by the movement of a fluid.
  5. 11. a measure of the average kinetic energy of the particles of a substance.
  6. 12. a material that does not conduct heat well
  7. 14. the number of wavelengths that pass a fixed point each second. It can also be thought of as the number of times a wave repeats in a given amount of time
  8. 17. a material that conducts heat well.
  9. 19. a state of matter that has a definite shape and a definite volume.
Down
  1. 1. the dense part of a longitudinal wave
  2. 2. the transfer of the energy of a wave to a material it encounters.
  3. 4. the bouncing back of a wave when it hits a surface through it cannot pass.
  4. 5. a state of matter that has no definite shape or volume.
  5. 7. the transfer of energy by electromagnetic waves.
  6. 10. the lowest point on a transverse wave.
  7. 13. the areas of a longitudinal wave between the compressions.
  8. 15. the bending of waves as they enter a new medium at an angle, caused by a change in speed.
  9. 16. the transfer of energy from one particle of matter to another by direct contact of the particles.
  10. 18. a state of matter that has no definite shape but has a definite volume.
