Convection ovens cook food more evenly than a standard thermal oven. Which statement explains how a convection oven works?

Question

A. Hot air is transferred when heat radiates from a thermal burner.
B. Hot air is transferred through direct molecule contact.
C. Hot air is transferred through density differences when cool air rises and hot air sinks.
D. Hot air is transferred through density differences when hot air rises and cool air sinks.

Answer 1

The correct statement that explains how a convection oven works is:

D. Hot air is transferred through density differences when hot air rises and cool air sinks.

In a convection oven, a fan circulates hot air throughout the cooking chamber, ensuring that heat is distributed evenly and allowing food to cook more uniformly. Hot air rises, and as it does, cooler air is drawn down, creating a consistent flow of heat around the food.
