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?
Salt water ice is stronger because of the high amount of sodium. Sodium has a lower freezing temp. than water/H2O *Sodium, being a metal and a solid at 0oC, has a HIGHER freezing/melting point than water. Sal ice is stronger because the ions and water molecules can more efficiently fit and bond together than in pure ice (the same reason ice is less dense than the same amount of water), so each part is attached to more of the other parts more strongly, and this makes it stronger.
Take 2 cups and fill them with water
Put a table spoon of salt in one and leave the other one like it was. Freeze them for a couple hours or until frozen. After they are frozen, take a knife preferably a table knife and stab at both of them repeatedly. Which yields easier to your stabbing, the salt water one or the fresh water? Try it!
When frozen, saltwater is colder. The reason why saltwater is colder when it it frozen is because of the salt in it, that type of water has to be at a lower temperature than freshwater to get to its freezing point.
Saltwater can get hotter (before boiling) than fresh water.
colder, is a temperature term 10 degrees is 10 degrees without regard to salt content.
The melting point of salted water is lower.
fresh water
Yes, but they can also be salt water.
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
Rinse it of with fresh water.
There is salt water and fresh water. Fresh water is only about 3% of the water in the world, and salt is about 97%. Of the 3% of fresh water, about 67% is in glaciers and ice caps. Hope this gives you what you're looking for. ;D Kay_kay
The Arctic ocean, and the Southern Ocean that surrounds Antarctica, are both salt water. The ice sheet that covers 98% of the continent of Antarctica holds about 70% of the earth's fresh water.
Yes, but they can also be salt 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.
Yes, icebergs are fresh 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
A2. The freezing point of salt water is lower than that of fresh, so when salt is added, it interacts with the ice to make salt water.
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.
