NaOH+Hcl=NaCl+H2O is an example of double displacement equation.
This reaction is exothermic as it releases some heat while producing NaCl and H2O.
Exothermic reactions are those which lead to the release of energy in the form of heat or light.
Endothermic reactions require heat to produce chemical products.
Since the reaction between sodium hydroxide and hydrochloric acid is an example of exothermic reaction therefore the temperature of the solution after the reaction appears to be high.
