A thick wall made of refractory bricks (k = 1.0 W/m K and = 5.08

A thick wall made of refractory bricks (k = 1.0 W/m · K and α = 5.08 × 10^-7 m²/s) has a uniform initial temperature of 15°C. The wall surface is subjected to uniform heat flux of 20 kW/m². Using EES (or other) software, investigate the effect of heating time on the temperature at the wall surface and at x = 1 cm and x = 5 cm from the surface. Let the heating time vary from 10 to 3600 s, and plot the temperatures at x = 0, 1, and 5 cm from the wall surface as a function of heating time.
