Question

Which of the following is an example of heat transfer by convection?

a. Water within a pan is heated and flows in a circular path.
b. Seawater is drawn into a mid-ocean ridge, heated, and rises.
c. The rise of material beneath mid-ocean ridges is coupled with subduction.

Answer 1

Answer: A. water within a pan is heated and flows in a circular path.

Explanation: Convection is a type of heat transfer that occurs in liquids and gases. Convection occurs when there is a contrast in temperature between two parts of a liquid or gas. The hot part of a fluid rises above, and the cooler part sinks to the bottom resulting to circular motion of the fluid.
