The length of a metal rod is 20 cm and its area of cross-section is 4 cm^2. If one end of the rod is kept at a temperature of 100^{\circ} C and the other end is kept in ice at 0^{\circ} C, then the mass of the ice melted in 7 minutes is (Thermal conductivity of the metal =90 Wm ^{-1} K^{-1} and latent heat of fusion of ice =336 \times 10^3 Jkg ^{-1} )

The length of a metal rod is 20 cm and its area of cross-section is 4cm2. If one end of the rod is kept at a temperature of 100∘C and the other end is kept in ice at 0∘C, then the mass of the ice melted in 7 minutes is (Thermal conductivity of the metal =90Wm−1K−1 and latent heat of fusion of ice =336×103Jkg−1 )
