1. It is generally believed that water freezes at zero degrees Celsius because ice melts at 0 degrees Celsius? Is that true? But I remember reading somewhere that water that is carefully cooled can remain in its liquid state at a temperature as low as minus 40 degrees Celsius.How does this happen? Besides is that how sea water doesn't freeze? I mean wouldn't the fish freeze up and die? Or or do their proteins and DNA play a role to prevent the animals from freezing?
2. What if I placed some frozen ice cubes in a cup of cold water and quickly chucked it in the freezer? Would the liquid water still freeze?
3. You know how normal water expands when we freeze it? Does the same concept apply to a solvent like salt water, cause isn't there something like sodium chloride in salt water?
Any help would he greatly appreciated, thanks in advance. =]
