What type of heat transfer is used when cooking on a barbecue grill?

* Conduction: The heat from the hot coals or gas flames directly transfers to the food through contact. The metal grates also conduct heat, further transferring it to the food.

* Radiation: The hot coals or gas flames emit infrared radiation, which heats the food directly. This is particularly significant in grilling, as the infrared radiation penetrates the food, contributing to its browning and cooking.

While convection (heat transfer through the movement of fluids) also plays a minor role in grilling, its contribution is less significant compared to conduction and radiation.
