  1. Properties of Liquids

  2. Surface Tension • Result of an inward pull among the molecules of a liquid that brings the molecules on the surface closer together • Water forms droplets and can bead up on surfaces • Strong attractions between water molecules cause molecules at the surface to be pulled slightly toward the molecules beneath the surface • Due to surface tension, the surface of water can act like skin • Ex: needle floating on water • Ex: Water strider walking on water

  3. Viscosity • A liquid’s resistance to flow • Depends on size and shape of particles and the attractions between the particles • Liquids with high viscosity flow slowly • Ex: honey • Liquids with low viscosity flow quickly • Ex: water, vinegar
