Understanding Chemical Energy and its Applications

The video explains that matter is composed of atoms, which form bonds containing chemical energy. This energy is released during combustion, such as burning wood or fuel, converting into heat energy. Chemical energy is also crucial in daily life, as it is released when digesting food and used for physical activities.
