This is because of the salt in the water
Ocean water contains salt, which lowers its freezing point compared to fresh water. This is because salt disrupts the formation of ice crystals, requiring colder temperatures for freezing to occur in ocean water.
Evaporates as the water is frozen.
Ocean water has a lower freezing point than fresh water due to the presence of salt, which lowers the freezing point of water. The salt in ocean water lowers the freezing point by making it more difficult for water molecules to form solid ice crystals. This is why ocean water typically needs to reach a lower temperature to freeze compared to fresh water.
Because of the colligative properties, ocean water's freezing point is below that of normal "pure" water. The salts disrupt the formation of a lattice, and it requires a lower temperature for the water to freeze.
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.
The coldest ocean is the Arctic Ocean. It is by the artic.
It depends. If the river is in the mountains or near the Poles than it's probably colder but if the ocean is like the arctic ocean or something like that then that's probably colder
It was cold because the sinking was in April, the early spring, and it was in the North Atlantic Ocean. Salt water has a lower freezing point than fresh water - what this means is, if you imagine being in a wading pool of ice cubes, the water that night would have been COLDER than that.
Salty ocean water has the lowest freezing point among the three options due to the presence of dissolved salts like sodium chloride. The salt lowers the freezing point of water, making it freeze at a lower temperature compared to fresh water.
the ocean has changed so in places it is warmer and other places it is colder than before. this is due to global warming.
Ocean temperatures can vary widely depending on location and depth. Surface temperatures can range from below freezing in polar regions to over 90°F in tropical areas. Deeper ocean waters tend to be colder, often around 36-37°F in the deep ocean.
It gets colder because the Sunlight heats the ocean and the deeper you go, the less penetrating the Sunlight is, therefore making the ocean water colder.
