Answer:
The chemical reaction in which the heat is absorbed. In this the heat is applied to the reaction as reactant these type of reaction is endothermic reactions.
These reactions lower the temperature of their surrounding area, thereby creating a cooling effect.
- Enthalpy change (ΔH) is positive
Example:
NH4Cl (s) + H2O (l) ➡ NH4Cl (aq) – Heat
