GENERAL KNOWLEDGE

Detailed explanation-1: -Chemical energy is energy stored in the bonds of chemical compounds, like atoms and molecules. This energy is released when a chemical reaction takes place. Usually, once chemical energy has been released from a substance, that substance is transformed into a completely new substance.

Detailed explanation-2: -The potential energy of chemical energy is found stored in the chemical bonds that bind atoms in molecules. Breaking these bonds apart or reforming them by adding fuels or reactants releases the chemical energy in the bonds.

Detailed explanation-3: -Chemical energy is energy stored in the bonds of atoms and molecules. Batteries, biomass, petroleum, natural gas, and coal are examples of chemical energy. For example, chemical energy is converted to thermal energy when people burn wood in a fireplace or burn gasoline in a car’s engine.
