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/∆T
Q = heat transfer rate
h = convection heat-transfer coefficient
A = exposed surface area
∆ T = temperature difference
