Question

what is convection???​

Answer 1

Answer:

Convection is the transfer of heat due to the bulk movement of molecules within fluids, including molten rock. Convection includes sub-mechanisms of advection, and diffusion. Convection cannot take place in most solids because neither bulk current flows nor significant diffusion of matter can take place.

Formula

Q=h A \Delta T

Q = heat transfer rate

h = convection heat-transfer coefficient

A = exposed surface area

\Delta T = temperature difference
