Question

One end of a $0.25 m$ long metal bar is in steam and the other end is in contact with ice. If $12 g$ of ice melts per minute, what is the thermal conductivity of the metal? Given cross-section of the bar $= 5 \times 1 0^{- 4} m^{2}$ and latent heat of ice is $80 c a l / g$ .

80 c a l / s - m -^{\circ} C

90 c a l / s - m -^{\circ} C

70 c a l / s - m -^{\circ} C

60 c a l / s - m -^{\circ} C
