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
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.
The dissolution of ammonium nitrate in water is an endothermic reaction. This can be determined by the observation that the flask becomes cold when the ammonium nitrate is dissolved. During an endothermic reaction, energy is absorbed from the surroundings, resulting in a decrease in temperature. In this case, the dissolution of ammonium nitrate requires energy from the surroundings, which is why the flask feels cold.
To determine whether the dissolution of ammonium nitrate in water is an endothermic or exothermic reaction, we need to understand the concept of temperature change during a reaction.
When a chemical reaction absorbs heat from its surroundings, it is called an endothermic reaction. In contrast, when a reaction releases heat to its surroundings, it is called an exothermic reaction.
In the case of ammonium nitrate dissolving in water, the dissolution process absorbs energy from the surrounding environment, causing the flask to become cold. This indicates that heat is being absorbed from the surroundings, which suggests that the reaction is endothermic.
So, the dissolution of ammonium nitrate in water is an endothermic reaction because it absorbs heat from its surroundings, resulting in a decrease in temperature as observed in the flask.
