Задача id13925

A steel rod of length l = 20 cm with a cross-sectional area S = 3 cm2 is heated at one end to a temperature t1 = 300°C, and the other end rests against ice. Assuming that heat transfer occurs exclusively along the rod (without losses through the walls), calculate the mass m of ice that melted in time t = 10 minutes. Thermal conductivity of steel k = 0.16 cal/(s•cm•K).
