What property of heat is illustrated when food is cooked on a gas grill?

The property of heat illustrated when food is cooked on a gas grill is conduction and convection. Conduction occurs as the food makes direct contact with the hot grill grates, transferring heat to the food. Additionally, convection plays a role as the hot air generated by the flame circulates around the food, cooking it evenly. Together, these heat transfer processes ensure that the food is cooked thoroughly and develops desirable flavors and textures.
