Which type of oven circulates heated air around the food that it cooks?

• A. Conventional
• B. Microwave
• C. Convection
• D. Steam

Answer: (C)

Circulating heated air around the food is the defining feature of convection cooking. In a convection oven, a built-in fan moves hot air around the food, which speeds heat transfer and results in more even cooking and browning on all sides. This is different from a conventional oven, which relies on radiant heat from elements and natural air flow without forced circulation. A microwave heats food by exciting water molecules with microwave energy, not by surrounding it with hot air. A steam oven cooks with steam, using moisture rather than dry hot air to transfer heat. So convection is the best choice because it specifically uses air movement to transfer heat evenly and create browning.
