You have two beakers. One contains pure water, the other contains pure methanol (wood alcohol). The covalent bonds of methanol molecules are nonpolar, so there are no hydrogen bonds among methanol molecules. You pour crystals of table salt (NaCl) into each beaker. Predict what will happen.
A) Equal amounts of NaCl crystals will dissolve in both water and methanol.
B) NaCl crystals will NOT dissolve in either water or methanol.
C) NaCl crystals will dissolve readily in water but will not dissolve in methanol.
D) NaCl crystals will dissolve readily in methanol but will not dissolve in water.
E) When the first crystals of NaCl are added to water or to methanol, they will not dissolve; but as more crystals are added, the crystals will begin to dissolve faster and faster.

The Functions of Water in the Body
Coolant circulates through the water jackets in the engine block and cylinder head.
Water vapor is supplied to the atmosphere by local evaporation or horizontal transport (advection).
Waterspouts are tornadoes that occur over warm-water bodies, instead of over land.
The chemical structure of the water molecule facilitates life
