A grill primarily uses conduction to transfer heat from the hot coals or flames to the food being cooked. Heat is transferred through direct contact between the food and the grill grates.
Conduction is the type of heat transfer where heat energy is carried by particles. It occurs through direct contact between particles, causing them to transfer heat energy from one another.
Radiation is the type of heat transfer that occurs in the form of waves. This transfer of heat can occur through empty space and does not require a medium. Examples include sunlight and heat transfer from a fire.
The sun heating a lake is an example of heat transfer through radiation.
Cooking on a grill involves all three types of heat transfer: conduction (direct contact between the food and the grill grates, transferring heat), convection (hot air circulating around the food, cooking it), and radiation (infrared heat from the grill's flames or heating element penetrating and cooking the food).
The Sun's heat reaches the Earth through radiation, which is a type of heat transfer where energy is transmitted in the form of electromagnetic waves.

It is radiation, as that is the only heat transfer that can occur in a vacuum (the universe).

Grilling over a charcoal flame involves heat transfer primarily by conduction. The heat from the burning charcoal is transferred to the grill grate, and then from the grate to the food through direct contact. Convection and radiation also play a role in cooking food on a charcoal grill by circulating hot air and emitting infrared heat.
Convection is one of the three main modes of heat transfer, alongside conduction and radiation. In convection, heat is transferred through the movement of fluids like air or water. The importance of convection as the main type of heat transfer depends on the system and conditions involved.
