cohesion attraction between molecules of the same substance, creates surface tension
adhesion attraction between different kinds of molecules
high specific heat water resists heating and cooling
density of ice solid water is less dense than liquid water due to shape of water and hydrogen bonding
evaporative cooling as water evaporates, its remaining surface cools
capillarity the rise of the surface of a liquid within thin tubes
good solvent many molecules dissolve in water
