ANATOMY

Detailed explanation-1: -Chemical reactions that absorb (or use) energy overall are called endothermic. In endothermic reactions, more energy is absorbed when the bonds in the reactants are broken than is released when new bonds are formed in the products.

Detailed explanation-2: -Matter can absorb any amount of energy. Light is a wave. An electron is a particle. Energy and matter are unrelated.

Detailed explanation-3: -Matter can change from one state to another when thermal energy is absorbed or released. This change is known as change of state. The graph in Figure 11 shows the changes in temperature as thermal energy is gradually added to a container of ice. heated, it absorbs thermal energy and its temperature rises.

Detailed explanation-4: -Matter is the material substance that constitutes the observable universe and, together with energy, forms the basis of all objective phenomena. Energy, in physics, is the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms.
