Because salt molecules dissolve in water, the charged ions that make up the salt molecules break apart, taking up heat from the water.

A Daily Antidote to Everything Else
Because salt molecules dissolve in water, the charged ions that make up the salt molecules break apart, taking up heat from the water.
Very cool. (No pun intended.)
Chemical salts have been used in this way for many years! Large cooling HVAC units use this way and then use heaters to dry out the chemicals after the “ENDOTHERMIC” reaction takes place for the cooling cycle.
GOOGLE: “…Industrial endothermic chemical chillers primarily utilize salts like ammonium nitrate (NH4NO3), ammonium sulfate (NH4SO4), urea, and ammonium chloride (NH4Cl). These salts, when dissolved in water, undergo an endothermic reaction, absorbing heat from their surroundings and causing a cooling effect.
Elaboration:
Ammonium Nitrate (NH4NO3): A common salt used in instant cold packs and other cooling applications. When it dissolves in water, it absorbs heat, resulting in a cooling sensation.
Ammonium Sulfate (NH4SO4): Another fertilizer-based salt that can be used for cooling.
Urea ((NH2)2CO): Found in some commercial cold packs and can also be used for cooling.
Ammonium Chloride (NH4Cl): Another salt known for its ability to absorb heat when dissolved in water.
Other Salts: While the above are most common, other salts like potassium chloride (KCl) and potassium sulfate (K2SO4) can also be used in endothermic cooling systems…”
I’m puzzled why anyone thought this new…
