Zero deg. F.*
The original definition of zero fahrenheit, centuries ago was "the lowest temperature achievable in a laboratory using salt (NaCl) and ice or snow". Modern science has shown that a saturated salt solution actually freezes at a few degrees below zero. For practical purposes: melting snow on roads and walks or making ice cream, one can use zero F., -18C. Sea, ocean water freezes at 28 deg. F. ,-2 deg. C.
What else can I help you with?
Why did the salt water freeze but the salt did?
Salt lowers the freezing point of water, meaning it needs to be colder for the salt water to freeze compared to pure water. The salt itself does not freeze because its freezing temperature is much lower than that of the salt water solution.
Does salt water freeze at the same temperature as normal water?
no, because if you put saltwater and freshwater in the freezer saltwater will not freeze completely ,because it has salt in it and it will not freeze at the same rate as freshwater that is my answer to this question.
Does water that is denser than normal like salt water freeze faster?
On the contrary, it takes longer for salt water to freeze - it freezes at a lower temperature than fresh water does.
What temperature does ice become water?
Depends on how pure the water is. If the water is 100% pure then then it will freeze at 0 degrees. IF it has a small amount of salt added to it, it might freeze about -3 degrees Depends on how pure the water is. If the water is 100% pure then then it will freeze at 0 degrees. IF it has a small amount of salt added to it, it might freeze about -3 degrees
Is salt water colder then ice?
well for something to freeze it has to be 0 degrees or lower which is what ice is, frozen water. so the water has to be 1 degree or more to NOT freeze so the ice is colder than salt watercoz salt water is not frozen... does t6hat make sense? Actually, salt water CAN be colder than ice because the salt lowers the freezing point of the water.
What substance can be added to water to make it freeze at a lower temperature?
Salt, alcohol, ethylene glycol, to name a few.
Why did the salt water freeze but the salt did?
Salt lowers the freezing point of water, meaning it needs to be colder for the salt water to freeze compared to pure water. The salt itself does not freeze because its freezing temperature is much lower than that of the salt water solution.
Why water freezes before salt water?
Water freezes before salt water because adding salt lowers the freezing point of water. This means that salt water needs to reach a lower temperature in order to freeze compared to pure water. As a result, pure water will freeze at a higher temperature than salt water.
What edible substance can be added to food to make it freeze at a lower temperature?
salt
Does salt water freeze at the same temperature as normal water?
no, because if you put saltwater and freshwater in the freezer saltwater will not freeze completely ,because it has salt in it and it will not freeze at the same rate as freshwater that is my answer to this question.
Why does salt lower the freezing point of ice?
Salt lowers the freezing point of ice by disrupting the formation of ice crystals, making it harder for water molecules to bond together and freeze. This results in a lower temperature required for the water to freeze, allowing the ice to remain in a liquid state at a lower temperature when salt is added.
What are the constants between salt water and fresh water in regards to freezing?
The difference is that fresh water will freeze at 0.c and salt will freeze to a lower temperature due to the presence of impurities (salt).
Why the salt wates don't freez?
salt water freezes but it is well below the normaltemperature of 0degree centigrade..this is because the salt and water form a combination which freezes at temperature of about 23 degrees below zero
What is the temperature if you put salt in water?
Adding salt does not effect the temperature.Answer:Adding salt does not change the temperature at the time you add the salt, but it raises the temperature at which the water will boil
How long do it take salt water or water to freeze and which one freeze quicker?
Salt water takes longer to freeze than plain water because the salt lowers the freezing point of the water. The time it takes for either to freeze depends on the temperature of the environment and the concentration of salt in the water. Generally, plain water will freeze faster than salt water in the same conditions.
How does salt keep water from freezing on your roadways?
Salt lowers the freezing temperature of water, which means that it has to be colder for the water to freeze.
Can salt water freeze completely?
Yes, salt water can freeze completely. However, the presence of salt decreases the freezing point of water, so it will freeze at a lower temperature compared to pure water. This is why salt is often used to prevent roads from freezing in colder temperatures.
