When water has a substance dissolved in it, it freezes at a lower temperature. Salt water has salt dissolved in the water, so it freezes at a lower temperature than fresh water.
Sugar water freezes faster than salt water. However, regular tap water will freeze faster than either salt, or sugar water.
Fresh water will freeze faster than salt water, and at a higher temperature too. Why?Salt water is called salt water due to its containing dissolved salts -- usually Sodium Chloride (NaCl), but any other salts will do. When water freezes, the molecules link up into a crystal structure (ice). The atoms of any dissolved salts will interfere with the formation of the crystal, meaning more energy will have to be taken out (the temperature will have to drop lower) before salt water freezes.
Fresh water freezes at 0oC = 273 K Salt water freezes at about -4oC = 269K NB THere is a large body of chemistry dealing with cryoscopic constants; that is the depression of freezing point, between the pure substance and its dissolution . Similarly, there are also Ebullioscopic Constants dealing the with rising of boiling points between pure substances and solutions.
Salt water melts faster than fresh water because salt lowers the freezing point of water. This means that salt water needs to be even colder than fresh water to freeze, leading to a faster melting rate when exposed to warmer temperatures.
Strong salt water freezes faster than weak salt water, as the added salt lowers the freezing point of the water. Therefore, strong salt water will reach freezing temperature quicker than weak salt water, coke, or Kool-Aid.
I think it is fresh water freezes faster because the salt melts ice.
Fresh water
Salt Water
fresh water, because salt water is more dense
Fresh water freezes faster than salt water, yes.
Fresh water freezes at a higher temperature than salt water. This is because the presence of impurities in water lowers its freezing point.
Salt water freezes at a lower temperature than fresh water, so it typically takes longer for salt water to freeze compared to fresh water. This is because the presence of salt lowers the freezing point of water.
Fresh water, because aqueous solutions have depressed freezing points.
Fresh water freezes at 32°f (0°c) at sea level. Sea water freezes at 28.4°f (-2°c) at sea level. Salt water depends on the concentration of salt. At maximum saturation salt water (23.3% by weight) freezes at -5.98°f (-21.1°c).

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.
On the contrary, it takes longer for salt water to freeze - it freezes at a lower temperature than fresh water does.
