What is the formula used to calculate pressure in a liquid, and what do each of the variables represent Explain your answer using Pressure in liquids (physics only) and depth.

The formula for calculating pressure in a liquid is p = hρg, where p is the pressure in pascals (Pa), h is the depth of the liquid in meters (m), ρ is the density of the liquid in kilograms per cubic meter (kg/m³), and g is the gravitational field strength in newtons per kilogram (N/kg).

A strong answer should address (Physics only) Identify density in kilograms per metre cubed and depth in metres when using p = hρg directly. Use the context of Pressure in liquids (physics only) within Pressure and pressure differences in fluids (physics only), then state the relevant forces or motion reasoning with units where needed. The answer is correct when it names the key physics quantity, keeps force and pressure distinct, and links the conclusion back to the approved learning objective.
