This four minute animation describes the properties of water that support life these properties include solvency, cohesion and adhesion, high surface temperature, high heat. Seawater properties are valuable tools for tracing water parcels as differing water mass formation processes imprint different amounts of various properties on the.
The force of adhesion between water and wax is very small compared to the force of cohesion between water molecules as a result, rain doesn't adhere to wax it tends to form beads, or drops, with the smallest possible surface area, thereby maximizing the force of cohesion between the water molecules. Alcohols are soluble in water this is due to the hydroxyl group in the alcohol which is able to form hydrogen bons with water molecules alcohols with a smaller hydrocarbon chain are very soluble as the length of the hydrocarbon chain increases, the solubility in water decreases with four carbon. Capillary action is when water defies gravity for example when you put a straw in water this is beneficial because it helps water travel up the stems in plants in order to help the survive specific heat is the specific temperature at which a substance boils at, for example when sand is hot at the.
