Question

Distinguish between convection and advection for class7

Answer 1

Answer:

Convection is the movement of a fluid, typically in response to heat. Advection is the movement of some material dissolved or suspended in the fluid. So if you have pure water and you heat it you will get convection of the water. You can't have advection because there is nothing dissolved or suspended in the fluid to advect. If you have silt suspended in the water and heat it then you will get convection of the water and advection of the silt.

Convection always transfers heat in the vertical plane while Advection heat transfer differs from convection in that the movement of heat is confined to the horizontal plane.
