Vedclass · Answer

(A) Heat flows from a hotter part to a colder part. In liquids,if the lower part is heated,the liquid becomes less dense and rises,creating convection currents. By keeping the upper part hot and the lower part cool,the density of the liquid at the top remains lower than at the bottom,which prevents the formation of convection currents. This allows for the measurement of thermal conductivity without the interference of convection.

While measuring the thermal conductivity of a liquid,we keep the upper part hot and the lower part cool,so that:
