  4. 10. instrument used to measure atmospheric pressure
  5. 12. how much material is packed into a given space
  6. 13. the ability to float
  7. 14. a principle that states that upthrust is equal to weight of fluid displaced
  8. 17. the force exerted by fluids, usually upwards
  9. 18. a principle that states that a body displaces its own weight in fluid
