The figure shows a lagged bar XY of non-uniform cross section. One end X of the bar is maintained at $100^{{}^{{}^{\circ}}} \mathrm{C}$ and the other end Y at $0^{{}^{{}^{\circ}}} \mathrm{C}$ . The variation of temperature along its length from X to Y in steady state is best represented by the curve.
