Question

અનુભવીઓએ હરખચંદ શેઠને શું કહ્યું ?​

Answer 1

Explanation:

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.
