  1. How do atomizers take advantage of Bernoulli's principle?
  2. What can you tell about an object if you know the density?
  3. What is pressure measured by?
  4. What is a fluid?
  5. What is pressure?
  1. a if it would sink or float.
  2. b the flask at the top (when you squeeze it) creates a greater fluid speed which causes a lower pressure and the pressure in the bottle is greater and causes the liquid in the bottle to move up and out of the bottle.
  3. c Newtons
  4. d a material that can easily flow
  5. e The amount of force exerted on a surface

5 Multiple choice questions
