What is the freezing temperature of sea water?
408260
About -1.8 degrees C, due to the freezing point depression of the dissolved salt (that's why they salt roads in winter)

The answer to this is made tougher by the fact that the water will be freezing.  I mean how can you answer a question where the water is ice cold and use the data provided at STP?  Think you need to either re-read your question or provide a little more info.

Ice is already frozen, if you mean what temperature does water freeze at, then 32°F or 0°C or 273 K.

It depends on the mass. The latent heat of fusion of water (the energy required to freeze it) is 333.7 kJ/kg. That means to freeze one kilogram of water, it requires removing 333.7 kilojoules of energy.\n\nThis assumes that the water is already at freezing temperature. If not, energy must first be removed to get it at freezing temp.

Ice and water are at equilibrium at 32 F (0 C).  A mixture of water and ice cannot be cooled below this temperature.   Salt depresses the freezing point (which is why it is added to icy or snowy roads in winter), allowing lower temperatures to be achieved.  This makes the viscosity build of the ice cream (caused by churning of the mixture) to occur in a shorter period of time, and keeps the ice crystals that form in the ice cream smaller - resulting in a smoother texture.

I saw that on Natn'l Geographic, and it is below 32 degrees F, I was surprised because the water is that cold and don't freeze.

Freezing point depression constant for water: \n1.86 degrees C/m\ndepression = (1.86 degrees C/m)(.81 m)= 1.5 degrees C to correct significant figures.  \n0 degrees C is the normal freezing point.  \n0-1.5= -1.5 degrees C, the new freezing point.

Sodium Chloride (NaCl), or salt, lowers the freezing point of water.  Putting salt on ice turns it back into water UNTIL the temps drop below the point where the salt water will freeze again which is between -9°C (15°F) and -21°C (-6°F) depending on the amount of salt suspened in the water.

Depends on the tempertaure of the water amongst other things.

Water is a much more stable environment than living up in the wind and snow on land.\n\nIn freshwater systems, the water beneath the ice on lakes and rivers doesn't drop below about 4 C (around 40 F).  If it gets colder than that, the water freezes, and floats up to the surface to become part of the ice cover.\n\nSo the cold-blooded fish living in the water get their metabolism lowered by the cold temperatures, but they can still survive - even eating and swimming about (just ask any ice-fisherman).\n\nIf a lake or river freezes right to the bottom though, the fish don't survive.  They get frozen, and new fish either have to repopulate the area the next summer, or the water body remains fish free.\n\nThere are some fish (especially in Arctic waters) that produce anti-freeze like compounds in their blood to keep them from freezing solid.  In salt water, the water temperatures can drop below the freezing point of the blood in a bony fish.  Without these compounds, the fish would indeed freeze.  \n\nIn particularly cold waters, the fish hover almost motionless, their metabolisms so low that they are almost dormant.  Any sudden sharp jostle or even brushing against an icy outcrop can provide a nucleation site for ice crystals to form, and the fish can freeze solid in an instant.  I've seen videos of this happening, and its kind of freaky.

Temperature must get below 32 degrees Fahrenheit or 0 degrees Celsius.\n\nWhen it gets that cold, the H2O particles have more resistance moving around until they move around less and less until water freezes. The particles are still moving... just very slowly. The particles also get larger in this process; thus the reason why ice expands.

Yes.  Salt water freezes at a lower tempurature than fresh water. \n\nThat is why we use salt to melt ice on sidewalks in the winter.

Salt, NaCl, turns into Na+ and Cl- ions in water.\n\nThe ions changes the equilbrium of H2O melting and freezing.\nLiquid water is block by the ions, so it has a harder time freezing back onto the ice. Since the ions doenst slow down\nthe melting of ice, but slows down the freeze of water.\nThe ice now melts at below 0 degree.\n\nSo a normal ice water will be at zero degree.\nBut a salt put on the ice/water will melt more of the ice at a lower temp., about 7-10 degree colder, depenting on the ammount of salt and ice avalibale.

skin is primarily water so it stands to reason if too cold it will freeze as water does

The concentration of salt in seawater varies with temperature.  Because the Arctic and Antarctic oceans are colder than the Indian Ocean and South China Sea, the salt is less soluble.  By the same principle, seawater near the floor of the ocean would be less salty because it's cold down there.  Throw in a few baby volcanoes, the Atlantic rift and a few dozen fumaroles, etc...  Then, you would have to know how many liters of water are in the oceans and that quantity is constantly changing.  Now, are you talking about common NaCL?  Or do you want to include all the sulfates, carbonates, phosphates, etc... which are all in the ocean?  Thanks for the easy 2 points!

salt water will freeze, but at a much lower temperature than non salt water. the north polar ice pack is non salt water, and the saly wayer flows underneath it. submarines ofter pass under the pack while on patrol.

The coldest temperature that anything can reach is –273.15 °C. That is called "absolute zero". On the Kelvin scale, which uses the same divisions as the Celsius scale, it is zero, making the point at which water freezes 273.15 °K. Absolute zero is the point at which all atomic movement ceases, i.e. the atoms no longer move relative to one another.\n\nAny material can be heated or cooled to any temperature, as long as enough energy can be added or removed to do so. Materials left in an environment for long enough will reach the same temperature as their surroundings. This is known as reaching equilibrium with the environment.
