Answer 1

Endothermic reactions are reactions that require external energy, usually in the form of heat, for the reaction to proceed. ... In order to melt the ice cube, heat is required, so the process is endothermic. Endothermic reactionIn an endothermic reaction, the products are higher in energy than the reactants.

Answer 2

An endothermic process is any process with an increase in the enthalpy H of the system. In such a process, a closed system usually absorbs thermal energy from its surroundings, which is heat transfer into the system
