A 10-cm thick aluminum plate (rho=2702 kg/m^3, c_p=903 J/kg K, k=273 W/mK, and alpha=97.1x10^-6 m^2/s) is being heated in liquid with temperature of 500 C. The aluminum plate has a uniform initial temperature of 25 C. If the surface temperature of the aluminum plate is approximately the liquid temperature, determine the temperature at the center plane of the aluminum plate after 15 seconds of heating.
