hydrogen bonding
some argue that the hydrophobic interaction is mostly an entropic effect originating from the disruption of highly dynamic hydrogen bonds between molecules of liquid water by the nonpolar solute. a hydrocarbon chain or a similar nonpolar region of a large molecule is incapable of forming hydrogen bonds with water. introduction of such a non-hydrogen bonding surface into water causes disruption of the hydrogen bonding network between water molecules. the hydrogen bonds are reoriented tangentially to such surface to minimize disruption of the hydrogen bonded 3d network of water molecules, and this leads to a structured water "cage" around the nonpolar surface. the water molecules that form the "cage" (or clathrate) have restricted mobility. in the solvation shell of small nonpolar particles, the restriction amounts to some 10%. for example, in the case of dissolved xenon at room temperature a mobility restriction of 30% has been found. in the case of larger nonpolar molecules, the reorientational and translational motion of the water molecules in the solvation shell may be restricted by a factor of two to four; thus, at 25 °c the reorientational correlation time of water increases from 2 to 4-8 picoseconds. generally, this leads to significant losses in translational and rotational entropy of water molecules and makes the process unfavorable in terms of the free energy in the system. by aggregating together, nonpolar molecules reduce the surface area exposed to water and minimize their disruptive effect.

temperature and humidity determine many different crystalline forms. ice crystals are responsible for various atmospheric optics displays.









































ice clouds are composed of ice crystals, the most notable being cirrus clouds and ice fog. the slight whitening of a clear blue sky caused by ice crystals high in the troposphere can be a sign that a weather front (and rain) is approaching, as moist air is carried to high levels and freezes to ice crystals.

at ambient temperature and pressure, water molecules have a v shape. the two hydrogen atoms bond to the oxygen atom at a 105° angle.
