Question

Why is the melting of ice is an endothermic process?

Answer 1

Hint: Endothermic reactions absorb heat to cause a chemical process. Some of the common examples include Photosynthesis, melting ice, evaporation, sublimation, etc. Exothermic reactions may be defined as the reactions in which heat is given out or released. The most common examples of exothermic reactions are combustion and oxidation. That means if heat is absorbed, it is endothermic in nature and if heat is released it is exothermic in nature.

Complete Answer:
There are two types of processes:
Endothermic reaction: Any reaction or change during which energy within the sort of heat is absorbed
Exothermic reaction: Any reaction or change during which energy within the sort of heat is released
On a molecular level, chemical reactions happen when the reactant molecules hit enough energy to interrupt down existing chemical bonds in order that new ones can form. Every reaction includes equivalent components: two or more reactants and a change in energy.
Water molecules are arranged during a rigid state (ice). Next, we add heat, which may be a sort of energy. Let’s say we leave our ice sitting within the sun. The sun gives off heat, and therefore the ice absorbs this heat as a sort of energy. This energy breaks down the rigid bonds within the ice and causes the water molecules to move quicker and collide more often. As the temperature increases, the solid state of water that is ice starts to melt into a liquid that is water. Thus, we can say that melting of ice is an example of an endothermic reaction.

Note:
The melting of ice is an endothermic process. Ice requires some heat to melt as the absorbance of warmth will cause the breakage of bonds. When the freezing point is attained, ions or molecules within the solid-state break down and molecules become loosely packed.
