7. Pressure

📌Learn about Pressure
📝7.1 Pressure
📝7.2 Pressure Changes
💥define the term pressure in terms of force and area, and do calculations using the equation pressure = force/area.
💥explain how pressure varies with force and area in the context of everyday examples.
💥describe how the height of a liquid column may be used to measure the atmospheric pressure.
💥explain quantitatively how the pressure beneath a liquid surface changes with depth and density of the liquid in appropriate examples.
💥recall and use the equation for hydrostatic pressure p = ρgh.
💥describe the use of a manometer in the measurement of pressure difference.
💥describe and explain the transmission of pressure in hydraulic systems with particular reference to the hydraulic press and hydraulic brakes on vehicles.
💥 describe how a change in volume of a fixed mass of gas at constant temperature is caused by a change in pressure applied to the gas.
💥 recall and use p1V1 = p2V2.
