Question

What is convection?
Please explain the answer properly, I will mark you as brainlist.​

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.

Answer 2

Answer:

In fluids (liquids and gases together), the molecules themselves carry energy from a hotter region to a colder region. This process of heat transfer is called convection. Convection plays a major role in weather phenomenon, for example, the almost daily rainfall in equatorial regions.
