Transcript of Convection

So What is Convection ? Convection Is The Transfer Of
Heat From One Place To Another
By The Movement Of Fluids.
(Example;Liquids,Gases) So How Does Convection Takes Place ?
-Convection Takes Place Due To The
Expansion Of The Fluid.When The Fluid
Is Hot, Its Volume Will Increases.
This Means Its Density Had Decreases... Next,The Less Dense Fluid Then
Rises And Floats Up While The Denser
Fluid Flows In To Its Places.
This Is Convection. We Are Coming To The End Of The
Presentation.. Let Us Present You
