Fresh water freezes much much quicker.
Fresh water
There are both salt water and fresh water crocs.
they can be in salt water and in fresh water
When water freezes, it becomes less dense and expands. This creates a layer of insulating ice on top of bodies of water, which helps to protect fish and other aquatic organisms from extreme cold temperatures. If water did not expand when it freezes, ice would sink, potentially making bodies of water freeze from the bottom up and causing harm to aquatic life.
The property of water that allows fish to survive winter's freezing temperatures is that the density of ice (solid water) is less than the density of liquid water. Because of this, the surface layer of water in the lakes freezes, and floats on top of the liquid layer, thus allowing marine life to survive.
I think it is fresh water freezes faster because the salt melts ice.
Fresh water
Sugar water freezes faster than fresh water due to the presence of sugar molecules which disrupt the formation of ice crystals. This phenomenon is known as the Mpemba effect, where the solution with a higher concentration of solute freezes faster than the solution with a lower concentration of solute.
Salt Water
Fresh water freezes at a higher temperature than salt water. This is because the presence of impurities in water lowers its freezing point.
fresh water, because salt water is more dense
Fresh water freezes faster than salt water, yes.
Fresh water, because aqueous solutions have depressed freezing points.
Fresh water freezes faster than salt water because salt lowers the freezing point of water. When salt is dissolved in water, it disrupts the formation of ice crystals, requiring the salt water to become colder than fresh water in order to freeze. This phenomenon is known as the "freezing point depression."
Plain water freezes faster than dirty water because impurities in dirty water lower the freezing point, requiring it to be colder before it freezes. This means that plain water will reach its freezing point quicker and solidify faster.
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.
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).
