Why does minty gum make cold water colder?

Answer 1

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.

Answer 2

the biochemistry reacts with the gum and water in your mouth and gives off a cool sensation.... It does actually change the temp of the water
