"WebThanks that covers a lot. I suppose if the surrounding temperature were significantly high then heat will still be emitted(so still just as exothermic), but if it were super high then after the heat is emitted it'd get reabsorbed, and it's just boil and then you'd have an endothermic state of matter transition taking place at the same time as the exothermic chemical reaction " - Exothermic salt
