148185 A metal rod of length $10 \mathrm{~cm}$ and area of crosssection $2.8 \times 10^{-4} \mathrm{~m}^{2}$ is covered with nonconducting substance. One end of it is maintained at $80^{\circ} \mathrm{C}$, while the other end is put in ice at $0^{\circ} \mathrm{C}$. It is found that $20 \mathrm{gm}$ of ice melts in 5 min. The thermal conductivity of the metal in $\mathrm{Js}^{-1} \mathrm{~m}^{-1} \mathrm{~K}^{-1}$ is (Latent heat of ice is $80 \mathrm{cal} \mathrm{g}^{-1}$ ).
