Question:
What happens when you heat salt?


Replies:
Feng,

It will get very hot before it melts. At first, the salt particles may jump about and crackle as water (which may be trapped within the crystals) boils off. In time, if the heat source is sufficiently intense, the salt will melt and become a clear liquid. Though it will boil, I have never heated it to that point. Salt (NaCl) melts at 801 C (1474 F) and boils at 1465 C (2669 F).

Regards,
