Final answer:
Outcomes of hydrogen bonding in water include its high boiling point, ice being less dense than liquid water, and strong surface tension. As temperature rises, viscosity and surface tension decrease due to weakening hydrogen bonds.
Step-by-step explanation:
Hydrogen bonds in water lead to several important outcomes due to their relatively strong intermolecular force nature. One key outcome is water's high boiling point, which is unusually high for a molecule of its size. This is because more energy is required to overcome the strong hydrogen bonds between water molecules compared to other substances with weaker intermolecular forces. Another outcome is the lower density of ice compared to liquid water — a unique property among most substances. This is due to the hydrogen bonds forming a rigid lattice in ice that is less compact than the arrangement of molecules in the liquid state, allowing ice to float on water.
Surface tension is another result of hydrogen bonding in water, which is much higher in water than in liquids without hydrogen bonds. The strong attraction between water molecules produces a 'skin-like' effect at the surface, which can support light objects, such as a bug or a paperclip. Viscosity and surface tension both decrease with increasing temperature as the strength of hydrogen bonds is overcome by the kinetic energy of the molecules.
