Pressure is the amount of force exerted per unit area. It is measured in Pascals. Fluids like liquids and gases take the shape of their container and exert equal pressure in all directions. The deeper an object is submerged in a fluid, the greater the pressure it experiences from the fluid above it due to the fluid's weight. Denser fluids exert more pressure. According to Pascal's principle, a change in pressure anywhere in an enclosed fluid is transmitted equally throughout the entire fluid.

2. Pressure Pressure is the amount of force exerted on a certain area. The SI unit for pressure is Pascal (Pa). *Pressure= Force/Area P F A

3. Fluids A fluid is any material that can flow and that takes the shape of its container. Examples: Loquids- water and oil Gases- CO2 and oxygen

4. Pressure all around Fluids exert pressure equally in every direction. This may explain why bubbles are round.

5. Pressure and depth Pressure does not depend in the amount of the fluid but in the depth of that fluid. The deeper an object in a fluid, the more pressure the fluid exerts on the object .

6. Density and pressure Fluids with a greater density will exert a greater pressure.

7. Pascal's Priciple A change in pressure at any point in an enclosed fluid will be transmitted equally to all parts of the fluid. A clear example for this priciple is hydraulics .
