Boiling point (100 C; projected -68 C) Freezing point (0 C; projected -90 C) Much higher than expected (compared to other hydrides) Water exists in 3 phases within the critical temperature range that accommodates life Heat of freezing; only 1/7 that of evaporation Low; Water structure can move easily into ice
•Freezing point= melting point: 0°C (32°F) •Boiling point = condensation point: 100°C (212°F) • Freezing and boiling points of water unusually high Temperature - Freezing and Boiling Points
The higher the concentration of ions (or molecules) in solution the higher is the boiling point of the solution For seawater with a salinity of 35 the boiling point is higher by about 0 3 deg C 3 Freezing point depression 4 Seawater freezes at a temperature about 2 deg C lower than freshwater Air-Sea Equilibrium
Normal Water is sea water whose chlorinity has been adjusted to about 19 4 */00and accurately determined by either direct or indirect comparisons with the original standard prepared in 1902 Hence the chlorinitiesof allbatches have been independent of changesin the atomic weights
The melting and boiling points of some other substances with molecular weight close to 18 (see Table 1) are well below those of water; this can be attributable to their molecules not being polymerized Substance Formula Molecular weight Boiling point 0C Melting point 0C Water H2O 18 100 0 Ammonia NH3 17 03 33 35 -77 7
