Based on research, the saltwater will hold heat the longest because saltwater has more molecules than freshwater.

The heat capacity of freshwater is 4.182 J/(g K) and the heat capacity of salt water is 3.993 J/(g K). Therefore saltwater will heat up faster than freshwater. It is important to note that heat capacity is based on the mass of a material, not it’s volume.

thx! AimeeH said: Salt doesn’t make water colder. The addition of salt to water does decrease its freezing temperature so it will remain water (not ice) below 32 degrees.

Because salt lowers the melting point of water, if you add salt to ice, the ice will melt. Salty ice water can get much colder than regular water, though. While salty 0°F ice will still melt, its temperature won’t increase to 32°F like it would in regular water.

No, salt does not make ice longer. Salt causes ice to melt at a lower temperature than 0ºC (32ºF) this is why it’s used to melt ice on roads. However, as salt melts and dissolves ice it will lower the overall temperature making it colder.

Ocean water freezes just like freshwater, but at lower temperatures. Fresh water freezes at 32 degrees Fahrenheit but seawater freezes at about 28.4 degrees Fahrenheit , because of the salt in it. When seawater freezes, however, the ice contains very little salt because only the water part freezes.

intuition tells me that it would take between 2 weeks at a bare minimum, and about 3 months at the maximum end. Take total ocean volume and average temperature, convert to Kenetic energy, subtract from that the KE from ocean ice.

This rapid freezing is done by submerging the sample in liquid nitrogen or a mixture of dry ice and ethanol. American inventor Clarence Birdseye developed the “quick-freezing” process of food preservation in the 20th century.

If the water is initially hot, cooled water at the bottom is denser than the hot water at the top, so no convection will occur and the bottom part will start freezing while the top is still warm. This effect, combined with the evaporation effect, may make hot water freeze faster than cold water in some cases.

The presence of salt in water, though, reduces the freezing point of water. The more salt in the water, the lower the freezing point will be.

The salted cube melts faster. When you add salt it dissolves into the water of the ice cube. Salt water freezes at a lower temperature than the 32 degrees F at which freshwater freezes. This makes the ice with salt on it melt faster.

Hi, Salt decreases the freezing point of water, but does not keep it from freezing. If you make your own saltwater, you can use a lower concentration of salt compared to ocean water, thereby increasing the freezing point.

Unlike plants, animals can move so they would move as far as possible or be trapped and frozen when the ice sank. If ice did not float, life underwater would be impossible! Ice floats when water freezes on the top. It stays on the top and ice slowly gets thicker, freezing our lakes and ponds from the top down.

Icebergs are chunks of glacial ice that break off glaciers and fall into the ocean. When glaciers melt, because that water is stored on land, the runoff significantly increases the amount of water in the ocean, contributing to global sea level rise.

Icebergs are dangerous because they are huge and they float low in the water which can cause danger to the ships. They tend to flip over at times. When they flip over the energy is so great it can cause tsunamis and on occasion can trigger earthquakes.

The ice below the water is dangerous to ships. The sharp, hidden ice can easily tear a hole in the bottom of a ship. A particularly treacherous part of the North Atlantic has come to be known as Iceberg Alley because of the high number of icebergs that find their way there.

The last living survivor of the Titanic, Millvina Dean, has died at the age of 97 in Southampton after catching pneumonia. As a two-month-old baby, Dean was the youngest passenger on board the giant liner when it sank on its maiden voyage with the loss of more than 1,500 lives.

“Yes, like all things, eventually, Titanic will vanish entirely. It will take a long time before the ship completely disappears, but the decomposition of the wreck is to be expected and is a natural process,” Patrick Lahey, president and co-founder of Triton Submarines, told Business Insider.
