Convection ovens are ovens that are advertised to cook food more evenly than a standard thermal oven. Which statement best explains how a convection oven works?

Question

a
Hot air is transferred through heat being radiated from a thermal burner.
b
Hot air is transferred through molecule to molecule contact.
c
Hot air is transferred through density differences with hot air rising and cool air sinking.
d
Hot air is transferred through density differences with cool air rising and hot air sinking.

Answer 1

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

c Hot air is transferred through density differences with hot air rising and cool air sinking.

In a convection oven, a fan circulates the hot air, which helps to cook food evenly by distributing heat more effectively than in a standard oven. As the hot air rises, it creates a flow that brings cooler air down to be heated, promoting even cooking.
