Fresh water always freezes at 0℃‚ but that is not always so for water with salt inside. The higher amount of salt there is in the water‚ the more the freezing point decreases. So‚ salt water freezes later than freshwater. The exact measurement of how they impact each other is this: every 5 psu increase‚ the freezing point decreases by 28%.. In an ocean‚ there is frazil and brine. Frazil are ice crystals suspended in water‚ and they are made of nearly pure freshwater. Frazil is the first stages of
