salt makes the water colder because it has a special chemical .Salt and water combine to form a molecule. Salt has sodium (NA) which inhibits crystalines from forming. Salt water can also separate as can be observed by boiling salt water until the water is gone leaving only the salt in the pan. Whats not so obvious is that cold will also separate salt and water. The separated water molecules can freeze (form crystalines) because the sodium is no longer present. As the amount of salt in the water (concentration) increases, the lower the temperature needed to cause the separation. salt is super cool, and it makes the water really cold, so fast, that it doesnt have enough time to freeze. it just says woooah that salt is soo cool. If yu have both water and ice together, no salt, the molecules go between the two equally. The ice melts as fast as the water freezes. So the two are in equilibrium. Adding salt to the water changes the equilibrium. It disrupts it. The salt dissolves but it has no where to go. It can't bind with the water molecules. So there are then less water molecules to freeze solid with the ice. It won't turn to ice. SO you have more melting than freezing happeneing. SO then the temperature drops so there will ber a freezing to the ice solids. The water gets colder, dropping the freezing point.. The salt is taking up the space that the water molecules did, almost diluting them. You could say that there are the same number of molecules but now some are salt and some are water. The water molecules get replaced by the salt.

How do you make water cold?

An easy way to make water cold is to put it in the refrigerator. If this is not possible, adding colder water would make water colder. Actually, adding ice would make this process faster, as it is colder than cold water. And dry ice would make it cold even faster than ice (but dry ice is dangerous- be careful).


How do you make minty ice cube?

When you make the ice cube you could just add a bit of mint flavour in the water so it tastes minty.


Does dry ice make water colder?

Yes, it will make water colder.


How can you make hot water freeze once you touch it?

you look on you tube under intently frozen water you cant make hot water once you touch it because eat the moment it gets colder then it wont be hot water it will be cold water


Why does being wet make you cold?

Being wet makes you feel cold because water conducts heat away from your body faster than air. When water evaporates from your skin, it takes heat with it, making you feel colder.


Does relaxing your body help you warm up when your cold I find shivering makes me feel colder?

Relaxing your body will only make you colder,and shivering is your bodies response when it is cold and is ment to warm your body up a little.There is no way shivering can make your body colder.


Why does water freeze faster?

because water is generally cold unless heated in a kettle. Coffee on the other hand is warm when you make it so if the water is colder to start with it will take less time to freeze.


Why does mist make you feel colder?

Mist can be stated as a form of water vapour. It is included with water molecules. So naturally mist makes the temperature decreased and makes us feel cold.


How does humidity affect the experience of cold weather?

Humidity can make cold weather feel colder because it can increase the rate at which heat is lost from the body. High humidity can make it harder for the body to regulate its temperature, leading to a perception of colder temperatures.


How can you make water freeze faster?

to make water freeze faster you put it some place that's colder.


Is humid cold?

Humidity itself does not make the air cold, but it can make the air feel colder to our bodies because moisture conducts heat away from our skin more effectively than dry air. So, humid conditions can make us perceive the temperature to be colder than it actually is.


Is ice endothermic or exothermic?

Definitions Exothermic - accompanied by, or requiring, the release of heat. Endothermic - accompanied by, or requiring, the absorption of heat. Now, does the melting ice get warmer or colder? If it gets colder, then it is exothermic. If it gets warmer, then it is endothermic. Consider how we make ice - we put water into a cold place so that it gets colder with time.
