The correct statement that explains how a convection oven works is: Hot air is transferred through density differences when hot air rises and cool air sinks.
In a convection oven, there is a fan or multiple fans that circulate the air inside the oven. By circulating the air, the convection oven ensures that the hot air is evenly distributed around the food, which leads to more even and consistent cooking.
When the convection oven is turned on, the heating element at the bottom of the oven starts heating the air. As the air becomes heated, it becomes less dense and rises. The fan then helps to push this hot air towards the food. As the hot air circulates around the food, it transfers its heat energy to the food, resulting in even cooking.
At the same time, the cool air in the oven tends to sink towards the bottom due to its higher density. This continuous cycle of hot air rising and cool air sinking helps to ensure a constant flow of heat around the food, leading to more even cooking and browning.
Therefore, the transfer of hot air through density differences when hot air rises and cool air sinks explains how a convection oven works.
