Freezing point of sea water
Name: ken levine
I am trying to find the freezing point of sea water.
Can I get some help here? It's my first time trying this feature.
The freezing point of seawater depends upon it's salinity,
which is the amount of salt that it contains. Open ocean seawater
has a salinity of about 35 (no units are used for salinity
anymore, although you may see it called o/oo which means
parts per thousand or psu, which means practical salinity units.
Neither usage is now considered correct). Anyway, fresh
water freezes at 0 degrees Celsius and 35 water freezes
at about -2 degrees C. The decrease is linear so that water
with a salinity of 17 freezes at about -1 degree C.
