Answer 2

$\huge \text{Convection }$

✍ It is the process of transmission of heat with actual motion of heated particles convection takes place only in fluids.

$\huge \text{Convection\: Current }$

✍ When a liquid taken in a vessel heated by placing over a gas burner, liquid particles at the bottom get heated due to conduction through the vessels base.

✍ The density of liquid at the bottom of the vessel decreases and become lighter than that above. As a result the heated liquid rises upward with a relatively denser holder liquid most downward this moving liquid is called Convection Current.
