What energy transformation takes place in a charcoal grill?

In a charcoal grill, the combustion of charcoal takes place, which is an example of a chemical energy transformation. The charcoal, which is made up of carbon, reacts with oxygen from the air to produce carbon dioxide and release energy in the form of heat. This heat energy is then used to cook food placed on the grill. The chemical energy stored in the charcoal is transformed into thermal energy, which is used for cooking.
