Heat is transmitted from higher temperature to lower temperature through the actual motion of the molecules in
Convection
Heat is transferred from areas of higher temperature to areas of lower temperature by the actual motion of molecules through convection. Convection occurs in fluids (liquids and gases) where warmer particles move to cooler areas and vice versa. Thus, the correct answer is "Convection".
