Q
What is Convection?
A
Convection is the transfer of energy by heating due to the movement of particles in a fluid.
2
Q
Convection Process Step 1
A
Fluid next to the heat source warms up and gains energy
3
Q
Convection Process Step 2
A
Warm fluid expands
4
Q
Convection Process Step 3
A
Warm fluid becomes less dense
5
Q
Convection Process Step 4
A
Warm fluid rises
6
Q
Convection Process Step 5
A
Warm fluid is pushed along by more rising behind it
7
Q
Convection Process Step 6
A
Away from the heat source, fluid cools down and loses energy
