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. 👉Like us on Facebook:   / olevelacademy-116234893093796   👉Follow us on LinkedIn:   / olevelacademy   👉Follow us on Instagram:   / olevelacademy   👉Visit our website: https://academy.takhti.pk 👉Visit our website: https://www.takhti.pk
