Seawater does freeze, but it freezes at a lower temperature than pure water.
When compounds, like salt, are dissolved in water, it freezes at a lower temperature. This is called freezing point depression.
Seawater has a salinity of 3.5% and freezes at about 28 degrees F or -2 degrees C.

Why do rivers and lake freeze in cold regions but not sea water?
One Word Answer:The Salt Explanation:The disolved salt in the sea water acts as a physical barrier between the water molecules and makes it harder for them to bond together and form solid ice, significantly reducing the freezing temperature of the water. Note:Salt water will freeze, but it freezes at a much lower temperature than water without salt in it. Antarctica and The Arctic are both giant, frozen, solid blocks of frozen sea water. Note 2:Not all seas contain salt and will freeze nearly as easily any lake.
At what point does water freeze?
At sea level, water freezes at 32 F and 0 C.
Why doesn't spring water freeze?
If the temperature is below freezing a water supply will freeze in the cold weather. The water will not freeze if the temperature is 32 degrees or more.
What is the name of the temperature at which a mixture freeze?
The temperature at which a mixture freezes is called the freezing point. For instance, water freezes at 32 degrees F. at sea level.
What will happen if you cool water down below its melting point?
Depends on the pressure the water is under, but normal water will freeze.
What water will not freeze?
Sea water will not freeze.
What will freeze the fastest sea salt water tap water or sugar water?
i think tap water will freeze the fastest
Is the sea water easily freeze than pure water?
No, it is harder to freeze because of the salt content.
Why do most lakes freeze in winter but oceans do not?
A solution of salt in water has a lower freezing point than that of pure water. Presence of salt in the sea water causes a lowering of the freezing point. Lakes are mainly fresh water which will freeze at a higher temperature than sea water. Which means a fresh water lake will freeze over before the sea will because the temperature needs to be much colder to freeze sea water because of the salt dissolved in the sea water.
Why does sea water freezes faster than fresh water?
sea water doesnt freeze faster than fresh water, fresh water freezes faster than sea water as it has a lower freezing point than sea water has as sea water contains salt which makes the boiling/freezing points increase therefore making the sea water freeze at a lower temperature.
Do sea water freeze before fresh water?
No, sea water freezes at a lower temperature than fresh water, because of the minerals -- mostly salt -- contained in sea water. Sea water may not freeze until it reaches 27 or 28 degrees F. Fresh water freezes at 32 degrees F.
Will seawater expands when frozen into iceberg?
Sea-Water doesn't freeze
Does salt decrease the melting point of water?
Yes, sea water can freeze up to - 3 0C.
Why do freshwater lakes not freeze?
Fresh water lakes do freeze, but very salty waters and moveing water, like the sea, will not freeze except in critically cold conditions. The lake you are reffering to may have moving water running inside it, making movement.
Why is the freezing point of salt water important for animals living in the sea?
There are organisms living in the sea. When it is winter, the sea water will not freeze easily thanks to the salt in the sea water, which lowers the original freezing point, and therefore saving the animal's lives.
Will the dead sea freeze?
considering the salinity of the dead sea, we can say it would not freeze... also associating it with the principle of of highway deicing .... but salt water would freeze at temperature below 0 0 C .. since the sea is located in a geographical location that has an average temperature of 25 to 30 0 C . We can conclude It would not or never freeze..
Why do ponds often freeze in winter but the sea rarely freezes?
When it snows the ice only freezes the top leaving the bottom still water and when you crack that ice the water is still there and the fishes in the sea are still alive. :) i hoped you have learnt
