In convection, heat is transferred
In convection, heat is transferred
Open in App
Solution
The correct option is B Upwards
Convective heat transfer occurs within a fluid itself and it is carried out by transfer of one fraction of the fluid to the remaining portion. The transfer of molecules occurs during convection. Since the movement of particles constitutes convection, it is the macro form of heat transfer. Also, convection is only possible in fluids where the particles can move easily and the rate of convective heat transfer depends on the rate of flow to a great extend.
