A 0.0508 m thick aluminum plate is initially uniform in temperature at 27°C. Suddenly the plate is immersed in a convection environment T = 100°C, h=9,330 W/m2°C. Evaluate thermal properties of the plate at 27°C. Consider the following:

i) Determine the time (s) for the mid-plane temperature to reach 70°C.

ii) For the same time as in part (i), calculate the surface temperature (°C).
