Question

Chimneys, ventilators , sea breeze and trade winds depend on this bulk motion of molecules

Answer 1

Answer:

Convection is the transfer of heat due to the bulk movement of molecules within fluids (gases and liquids), including molten rock (rheid). Convection includes sub-mechanisms of advection (directional bulk-flow transfer of heat), and diffusion (non-directional transfer of energy or mass particles along a concentration gradient).
