Why does a glass of salt water get cooler as the salt dissolves in the water?
Megsmk
In general, salt water may be colder than distilled(pure) water because the salt water has a high concentration of dissolved ions within it causing its specific heat capacity to be lower than that of distilled water. That is to say, it takes less energy to raise the temperature of salt water then distilled water, which also means that distilled water can retain heat longer than salt water can. Dont really know if thats what you were getting at but there you go.

∙ 11y agoIf this is a fact, the only reason would be the presence of the ions sodium and chloride in the water. However I think that the question is a little wrong. When you put sodium chloride to ice, this will lower to temperature to around -20 degree Celsius, which is due to the bounding of the crystal, that need energy to go to the form of ions.

What dissolves faster in heated water sugar or salt?
Salt dissolves faster in heated water. Sugar dissolves faster in regular water.
What is produced when salt dissolves into water?
Salt Water
How does temperature affect how quickly salt dissolves in water?
the hotter the water or whatever liquid you use, the faster the salt dissolves
Will salt keep its physical properties in water?
no, salt dissolves in water.
Are all solids equally soluble in the same solvent?
Absolutely not! Using gasoline as a solvent, wax dissolves in it but glass will not dissolve at all. Using water as a solvent, salt dissolves in it but pepper will not dissolve at all. Using hydrofluoric acid as a solvent, glass dissolves in it but wax will not dissolve at all.
Sharon pours salt into a glass of water. The salt dissolves. The substance in the glass is?

What happens when a teaspoon of table salt is stirred into a glass of water?
It dissolves.
How do you separate salt and glass particles?
Ground salt is soluble in water, glass is not. Put the mixture in a strainer and run water over it for an extended period. Water. The salt dissolves, the glass doesn't.
What dissolves faster salt water or sugar water?
Salt dissolves faster in heated water. Sugar dissolves faster in regular water.
What dissolves faster in heated water sugar or salt?
Salt dissolves faster in heated water. Sugar dissolves faster in regular water.
What makes salt water denser than fresh water?
The salt in the water does this. Consider a glass of water filled up to a line on the glass. Then add 3 teaspoons of salt to that glass of water and stir until the salt dissolves. You will find that despite the addition of the salt the water still only comes up to the line. What has happened is that the salt has gone into solution in the water and the mass of the salt is now part of (inside) the water - the density of the solution has increased.
What is produced when salt dissolves into water?
Salt Water
How can you retrieve salt from broken glass?
A properties of compounds problem. Since salt dissolves in water, and glass does not you can dissolve the glass-salt mixture can then filter out the glass particles, then evaporate the salt solution, and you would get your salt. Though what I would do is buy more salt, and broken glass is never fun to play around with, even in chemistry class.
Why does water absorb salt?
Water "dissolves" salt. Water does not absorb salt.
What is a solvent solution?
A solvent is a substance that dissolves the solute in a solution. For example, in salt water, water is the solvent and the salt is the solute. Water dissolves the salt.
How does cold water affect how salt dissolves?
Cold water simply slows down the rate at which salt dissolves.
