question

A steel rod of length L = 20 cm and cross-sectional area A = 3 cm^2 is heated at one end to T_1 = 300°k while the other end rests in ice. Assuming that heat transmission occurs exclusively through the rod (without losses from the walls), calculate the mass m of the ice melting in time ∆t = 10 min. The thermal conductivity of steel is k = 0.16 cal deg^-1 sec^-1cm^-1.
