They are called hydrogen bonds. Many of water's unusual properties occur because of the attraction among its polar molecules. The properties of water include cohesion, adhesion, capillary action, surface tension, the ability to dissolve many substances, and high specific heat.
This section describes the properties of water in the liquid and solid states and explains how hydrogen bonding affects the surface tension and vapor pressure of water.
