When ammonium nitrate is dissolved in the water in a flask ,the flask becomes cold .is this an endothermic or exothermic reaction? How do you know

Answer 1

The dissolution of ammonium nitrate in water is an endothermic process. This can be deduced from the fact that the flask becomes cold during the reaction. Endothermic reactions absorb heat from the surroundings, resulting in a decrease in temperature.
