  1. Chapter 14, Section 1Fluids and Pressure

  2. All Fluids Exert Pressure • Fluids include liquids and gases. • Pressure is the amount of force exerted on a given area.

  3. The Formula of Force • Pressure = Force / Area • Force = Pressure x Area • The SI unit is the pascal (pa)

  4. Pressure and Bubbles • Fluids exert a push out in all directions. • This makes a round shape.

  5. Atmospheric Pressure • The atmosphere is the layer of gases that surrounds the Earth. • This layer causes a pressure called Atmospheric pressure.

  6. Density and Water Pressure • Pressure depends on the depth of the fluid. Lower depth = more pressure • Water and air combine to exert pressure.

  7. Pressure Differences and Fluid Flow • Fluids flow from regions of high pressure to regions of low pressure. • Example: breathing, drinking through a straw, tornadoes, etc.
