Suppose the length of rod, L = 50 cm is immersed in steam until its temperature is throughout u, = 100 °C. At time t = 0, its lateral surface is insulated, and its two ends are imbedded in ice at 0 °C. Calculate the rod’s temperature at its midpoint after half an hour if it is made of (i) iron (kiron = 0.15) (ii) concrete (kconcrete = 0.005)
