One end of a uniform well-lagged metal bar of length 0.80 m and cross-sectional area of
4.0 x 10-m” is kept in steam at 100 °C while the other end is in melting ice in a well-lagged
container. The ice melts at a steady rate of 5,5 x 10 * kgs and the thermal conductivity of
the material of the bar is 401 Wm''K! Calculate the specific latent heat of fusion of ice.
