,high-specific heat, high heat of vaporization, the lower density of ice
and High polarity.
-Water's attraction to other water molecules, is one of the major properties of water. Water's polarity lends it to be attracted to other water molecules. The hydrogen bonds in water hold other water molecules together.
-Water's attraction between molecules of a different substance is called adhesion. Water is adhesive to any molecule it can form hydrogen bonds with.
