Vedclass · Answer

(A) In liquids,heat transfer occurs primarily through convection if the bottom is heated,as the warmer,less dense liquid rises. By heating the liquid from the top,the warmer liquid stays at the top and the cooler,denser liquid remains at the bottom. This stable density gradient prevents the formation of convection currents,allowing for the measurement of thermal conductivity through conduction alone.

When measuring the thermal conductivity of a liquid,we should keep the top part hot and the bottom part cold so that...
