Question

Inside the oven heat moves in a circular motion. What type of heat transfer is occurring?

1) Conduction
2) Convection
3) Radiation
4) None of the above

Answer 1

Heat in an oven moves in a circular motion, which is an example of convection.

Step-by-step explanation:

Convection is the heat transfer by the macroscopic movement of a fluid, and it occurs when hot fluid rises and cold fluid sinks. In the case of an oven, the heat moves in a circular motion due to the rising hot air and sinking cold air. This is an example of convection.

When the air inside the oven is heated, it becomes less dense and rises, then cools and falls in a circular pattern, creating a convection current that evenly distributes the heat inside the oven.
