Chapter 19 - Liquids

Terms and Objectives

New terms in Chapter 19:

Archimedes' Principle buoyant force displace buoyancy
Principle of Flotation Pascal's Principle hydraulic press  

Chapter 19 Objectives:

When you complete chapter 19, you should be able to:

  1. ... describe how the pressure varies at different points in a fluid; in particular the relationship between pressure in a fluid and depth.
  2. ... state Archimedes' Principle.
  3. ... calculate the buoyant force on an object submerged in a fluid given its volume and the density of the fluid.
  4. ... tell whether an object will sink or float given its density and the density of the fluid.
  5. ... use the Principle of Flotation to determine the weight of fluid displaced by a floating object.
  6. ... use Pascal's Principle to determine the changes in pressure and force in a confined fluid.
