Document Summary

Shape and volume are well de ned a solid material is rigid it resists deformation solid/liquid/gas depend on the attraction between the molecules surface tension. Fluids ow and easily deform in response to an applied force, it takes the shape of the container. Liquid: - volume is (nearly) constant treat as incompressible. Gases have a much lower density both ow & both are considered to be uids. Liquids have a density around one thousand kg per cubic metre. Molecular motion of uid atoms/molecules collide with container walls - results in force on walls. Pressure can be de ned as the magnitude of normal force per unit area pressure is the same in every direction. Liquid exerts this pressure on any immersed surface. Units: p = [f / a] > [n/m^2] = pa other units: 1 atm = 1. 013 x 10^5 pa = 101. 3 kpa approx. Hydrostatic pressure: pressure in a uid depends on the depth.
