My fiance and I did an experiment with hot and cold water to see which one would make ice cubes faster. Honestly they froze at about the same time. He was taught that because its hot the molecules come together faster in the cold air, but during the test it was equal. As for the salt water I would think that would come in last.

Does hot cold or salt water freeze faster?
Cold water, being the closest to freezing point, will obviously freeze the fastest. Hot water will freeze the second fastest, and salt water barely ever freezes, except in very cold conditions.
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.
What is freezing point of water in both of C and F?
Under normal conditions, ordinary water freezes at 0°C, or 32°F. However, if you add salt to water, its freezing point becomes lower.
How do you make an egg sink?
An egg will sink in water but will float in salt water. An egg will sink faster in hot water than it will in cold water.
Is salt water more dense then cold water?
Yes, salt water has a greater density than fresh water. The ocean is about 2.5% denser than fresh water. This causes greater buoyancy of objects and a swimmer can notice this easily. Usually, when any solute is added to a solvent, the resultant solution increases in density, but there are exceptions to this rule. In the case of salt water, two things combine to cause the increase in density. First, a cubic centimeter of salt is about twice the mass of a cubic centimeter of water. Second, if you add a cubic centimeter of salt to a liter of water, the volume will increase by only about half a cubic centimeter. (This is because the dissolved sodium (Na+) and Chlorine (Cl-) atoms strongly interact with the polar water molecules causing rearrangement of water molecules near the ions which results in the nearby water atoms occupying a smaller volume.) If one is more precise about density, one needs to specify temperature. Cold salt water has a greater density than warm salt water; similarly for fresh water. Salt affects the temperature of water freezing and the density of water is peculiar near freezing anyway, so one needs to be careful when making general statements about water density and salt and temperature when the system is within a few degrees of freezing.
Why does water freezes faster then salt water?
the salt prevents the water from getting cold
Why did the salt water froze first?
First freezes the pure water !
Why is that ocean water freezes?
the reason salt water freezes is because of the amount of salt in the water
If you put salt on ice does it freeze or get cold faster?
Salt lowers the temperature at which water freezes which would cause the ice to melt.
What water freezes?
Any water that gets cold enough to freeze. You can freeze fresh water, brackish water, salt water, or polluted water.
How does fresh water freezes faster than salt water?
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.
Does hot cold or salt water freeze faster?
Cold water, being the closest to freezing point, will obviously freeze the fastest. Hot water will freeze the second fastest, and salt water barely ever freezes, except in very cold conditions.
Witch freeze faster cold water or hot water?
I believe hot water freezes faster because it is supercooled. Cold water is non-supercooled. When cold water freezes ice crystals form and float to the top, forming a layer of ice over the top of the water, so the layer of ice stops evaporation . While the hot water, which is probably no longer hot in the freezer,when it does freeze, it freezes throughout, creating more or less of a slush before freezing solid.
What freezes faster fresh water light salt water or heavy salt water?
I think it is fresh water freezes faster because the salt melts ice.
Why are rivers cold?
Rivers and streams are composed of fresh water which freezes at 32o F or 0o C, so if the water gets colder than that, it will freeze. Salt water freezes at a lower temperature (which is why salt is used to melt ice).
Does salt water or fresh water freezes faster?
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).
Alternate Wordings for 'Which freezes first cold water or hot water or salt water?
One alternate wording is At waters freezing temperaturethere are 3 test tubes, cold water is in test tube A, hot water is in test tube B, and salt water is in test tube C. Which test tube at (32 degrees) which will freeze the fastest? i hope i helped!
