Question
What is the term for the transfer of heat through the movement of fluids?
Solution
The term for the transfer of heat through the movement of fluids is called "Convection". Here are the steps that describe the process:
-
When a fluid (which can be a liquid or a gas) comes into contact with a heat source, it absorbs heat energy.
-
As the fluid heats up, it becomes less dense than the surrounding cooler fluid.
-
Because of this difference in density, the warmer, less dense fluid rises.
-
As the warmer fluid rises, it moves away from the heat source. The cooler, denser fluid then moves in to replace it.
-
The cooler fluid then comes into contact with the heat source and the process repeats.
-
This continual process of warm fluid rising and cool fluid sinking creates a cycle of heat transfer known as a convection current.
This is how heat is transferred through the movement of fluids in convection.
