1. Chapter 14, Section 1 Fluids 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
And 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.
