Is cooking food on a carcoal grill potential energy?

Cooking food on a charcoal grill involves both potential and kinetic energy. The charcoal itself contains potential energy in the form of chemical energy, which is released as heat when burned. Once ignited, this energy transforms into kinetic energy as the heat cooks the food. So, while the charcoal has potential energy before it is lit, the act of cooking involves the conversion of that energy into heat.
