  3. example of high specific heat
  4. Examples of mechanical waves
  5. Heat flow
  1. a always goes from hot to cold
  2. b Sound, ocean waves, earthquakes
  3. c 1) speed and frequency = directly proportional
    (as speed goes up, frequency goes up)
    2) wavelength and frequency = inversely proportional
    (as wavelength gets longer, frequency goes down)
