Which of the following is a unique property of water?

Question

Quizplus · Accepted Answer

Besides mercury, water has the highest surface tension for all liquids. Water's high surface tension is due to the hydrogen bonding in water molecules. When freezing, molecules within water begin to move around more slowly, making it easier for them to form hydrogen bonds with each other and eventually arrange themselves into an open crystalline, hexagonal structure. Because of this open structure as the water molecules are being held further apart, the volume of water (now ice) increases about 9%. This is why ice floats on liquid water.
Water also has an exceptionally high heat of vaporization. Vaporization occurs when a liquid changes to a gas.
