Revise Edexcel GCSE Physics 15.2.5 Pressure in liquids: depth and density with the question bank and revision guides.
Explain why the pressure in liquids varies with density and depth. • Use the equation to calculate the magnitude of the pressure in liquids and calculate the differences in pressure at different depths in a liquid: pressure due to a column of liquid (pascal, Pa) = height of column (metre, m) × density of liquid (kilogram per cubic metre, kg/m³) × gravitational field strength (newton per kilogram, N/kg); P = h × ρ × g.
