5b - density and pressure

state the word equation linking the terms density, mass and volume

density (g/cm³) = mass (g) / volume (cm³)

state the symbol equation linking the terms density, mass and volume

ρ = m/V

state the word equation linking the terms pressure, force, and area.

pressure (N/m²)(Pa) = force (N) / area (m²)

state the symbol equation linking the terms pressure, force, and area.

P = F/A

what is a fluid?

a liquid or gas

how does pressure in a fluid at rest act?

equally in all directions

state the word equation linking the terms pressure difference, height, density, and gravitational field strength

pressure difference (Pa) = height (of fluid above point) (m) x density (kg/m³) x gfs (N/kg)

state the symbol equation linking the terms pressure difference, height, density, and gravitational field strength

P = ρgh
