Vedclass · Answer

(D) The correct answer is $D$.Convection is the process of heat transfer by the actual movement of the molecules of a fluid (liquid or gas).The rate of heat transfer by convection depends on the temperature difference,the velocity of the fluid flow,and the heat capacity of the fluid.Thermal conductivity is a property associated with conduction,which is the transfer of heat through stationary matter by molecular collisions.Therefore,the thermal conductivity of the carrying medium does not affect the convection process.
