Chapter 14, Section 1 Fluids and Pressure

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

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

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

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

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

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.
