Explanation:
When you burn coal at a power plant, the heat helps to release some of the chemical bonds which radiates energy which releases even more bonds. Here, the chemical energy is converted into electrical energy.
When heat is added to fuel and oxygen, the atoms in the fuel are energized and start to break apart from one another. Once released, these atoms form new bonds with the oxygen. Energy is required to break the chemical bonds in the fuel (an endothermic process).
