A great question, but you asked it wrong. See if you follow this... the temperature of anything is just it's temperature. if something is negative 15 centigrade, and something else is also negative 15 centigrade, they are the same temperature. so, frozen salt water and frozen fresh water could be at the same temperature, no problem. or they can be a different temperatures, depending upon which one is chilled more, in a "stronger" freezer. what you meant to ask was this: does it take a lower temperature to freeze a equal volumes of salt water and fresh water? Salt blocks the formation of hydrogen bonds between the water molecules, which makes the water "hard" or frozen solid. To freeze salty water it takes a lower temperature than to freeze an equal volume of fresh water, because the fresh water has no salt ions to block the formation of the hydrogen bonds. Still, either salty water or fresh could be frozen solid, and at some point, say negative 15 centigrade or colder, both will remain frozen, and be at the same temperature. how was this?
Ice caps are made of fresh water. When this ice melts into the ocean, it contributes to the salinity of the water in that area.
I think that salty ice cube do float in water because ice bergs float it water and they're made of salty water. i think i depends on the density (Amount of salt) in the ice
Salt water. The salt makes it melt faster, than pure fresh water.That is rubbish. Salt crystals may be spread onto ice to melt it (causing a drop in temperature too). A mixture of crushed ice and salt is commonly used as a "freezing mixture" in the laboratory. However, a lump of ice (of a given mass and temperature) will not melt at any appreciably different rate in a bath of salty water than in a bath of fresh water at the same temperature. This is because the thermal conductivity of salty water is only very slightly greater than that of fresh water, but the thermal capacity of salty water is less than that of fresh water, so any effects due to these differences tend to cancel each other out. The main factor that would influence the rate of melting would be the temperature of the water bath. Some experiments have shown that if the bath water is salty enough, the bath water is more dense than any cold, recently-melted water from the ice cube and thus there will be no convection currents which might carry heat away quicker than by conduction alone, from which the obvious conclusion is that the ice should melt quicker in fresh water.
When ice caps melt, fresh water from the ice flows into the ocean, diluting the salt concentration. This influx of fresh water reduces the overall salinity of the surrounding seawater. Additionally, the melting of ice caps can disrupt ocean currents and circulation patterns, further affecting the distribution and concentration of salt in the ocean.
The Southern Ocean that surrounds Antarctica is a salt-water ocean. The ice sheet that covers 98% of Antarctica is frozen fresh water.

salt water ice and fresh water ice
salt water is densest
yes
In the world,1% is fresh water,2% ice, and 97% salt water.
It's not the color that is significant, its the fresh water that the ice cubes were made with. Salt water is heavier than fresh water so the fresh water floats a top the salt water.
I think it is fresh water freezes faster because the salt melts ice.
When ice forms in a salty body of water such as the ocean, the salt remains in the liquid portion of water underneath the ice, and the ice is pure water.
The Southern Ocean that surrounds Antarctica is salt water, the saltiest ocean water on earth. The ice sheet that covers 98% of the Antarctic continent is fresh water -- the store of 60%-70% of all the fresh water on earth
Yes, salt water ice cubes melt more slowly than fresh water ice cubes because the addition of salt lowers the freezing point of water, requiring more energy to melt. This makes the salt water ice cubes colder and more resistant to melting.
Tap water is fresh water. The phrase "fresh water" refers to water with very little or no salt in it (as opposed to salt water, such as is found in oceans). Tap water contains little or no salt, and is therefore fresh water.
