Performance Objectives

The student should be able to:

  1. Describe the method of heat transfer (convection) and state two of its applications

Content

Convection

Convection is the mode of heat transfer which occurs mostly in liquids and gases. In this method, heat transfer takes place with the actual motion of matter from one place within the body to the other from high temperature to low temperature. Often when we boil water we have seen bubbles and currents develop in the water on careful observation.

This is an apt example of the convection process. The hot water at the bottom becomes lighter and moves upwards forcing the cold and denser water at.... View More
