Thick slabs of stainless steel (k = 14.9 W/m·K and α = 3.95 × 10⁻⁶ m²/s) and copper (k = 401 W/m·K and α = 117 × 10⁻⁶ m²/s) are subjected to uniform heat flux of 8 kW/m² at the surface. The two slabs have a uniform initial temperature of 20°C. Determine the temperatures of both slabs, at 1 cm from the surface, after 60 s of exposure to the heat flux.
