Final answer:
Grilling and broiling are not the same; grilling cooks from below while broiling applies heat from above using radiation as the dominant heat-transfer method, creating a distinctive char and flavor.
Step-by-step explanation:
The statement that grilling and broiling are the same thing is false. Grilling typically involves cooking food from below, while broiling applies heat from above. In the case of broiling, radiation is the dominant heat-transfer method. This is because in broiling, a gas flame or an electric heating element produces very high temperatures very close to the food and mostly above it. Heat radiates directly from the heat source onto the food with minimal interference from the air or pans, since no direct contact is made between the cooking device and the food.
This direct radiation results in quick cooking times and often imparts a distinctive char and flavor to the food, making it a popular method for foods that benefit from a crispy exterior and a tender inside, such as steaks and other meats.
