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.
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
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.
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
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.
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 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 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).
Does salt water freeze faster or water?
'Faster' is not the correct word. Salt Water freezes at a lower temperature than pure water. (aqua puris). Salt water also boils at a higher temperature than pure water. There is a whole lot of chemistry dealing with the depression of freezing point, when a pure solvent is made into a solution with the dissolution of a solute. Pure water has nothing dissolved in it. Salt water is pure water (Solvent), with a quantity of salt (solute) dissolved in it. to form a solution. Freezing point of pure water is 0 oC Freezing point of saline water is ' -6 oC'. There is a whole lot of chemistry dealing with Cryoscopic Constants.
How long do it take salt water or water to freeze and which one freeze quicker?
It is NOT a case of 'longer' or 'quicker'. Salt water freezes at a LOWER temperature than pure de-ionised (distilled) water. The freezing point of pure de-ionised (distilled) water. is 0 oC salt water is ' -6 0C '. How long or quick it takes to go from 0 oC to -6 oC is a matter of time and the ambient temperature. NB There is a whole lot of physical chemistry devoted to the depression of freezing points Cryoscopic Constants. Conversely there is a whole lot of physical chemistry devoted to the elevation of boiling points Ebullioscopic Constants. pure water boils at 100 0C salt water boils at 102 oC (depending on conc'n of salt). The above temperatures refer only to water at standard temperature and pressure (STP).
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.
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.
