Question
The unusually high boiling point of water is evidence of high molecular weight induced dipole forces dispersion forces hydrogen bonds Ice floats in water because, all solids float in the liquid form of the same compound water expands as it is heated density of ice is greater than that of liquid water. the 3-dimentional arrangement of water in ice forces water to expand as it freezes How many atoms are in the unit cell of the following crystal formation? Identify which state(s) of mater are present in each region of the following plot of temperature versus heat added. This is a heating curve for water. Region A-B: Region B-C: Region C-D: Region D-E: Region E-F:Explanation / Answer
16. D
Hydrogen bonding is a very strong intermolecular force which holds water molecules together strongly. The partial positive charge on hydrogen and partial negative charge on oxygen of one water molecule exert a strong attraction to another water molecule. Now, to boil water, it has to escape the strong hydrogen bonding between molecules, hence, higher temperature is required. Therefore the hydrogen bonding results in a high boiling point of water.
