Vedclass · Answer

(B) In a steady state,the rate of heat flow $(H)$ through any cross-section of a conductor is constant,provided there is no heat loss from the curved surface. Since the problem states that the curved surface is thermally isolated from the surroundings,no heat escapes through the sides. Therefore,the heat flow rate $H$ remains the same at every cross-section along the length of the conductor. Consequently,the graph of $H$ versus $x$ will be a straight line parallel to the $x$-axis.
