Consider a large plane wall of thickness L = 0.2 m, thermal conductivity k = 1.2 W/mK, and surface area A = 15 m². Internally, the wall is assumed to generate heat at 500 W/m³. The left and right surfaces of the walls are exposed to convective heat transfer. On the left side (at x = 0 m), the wall temperature is maintained at 60°C. On the right surface side (at x = 0.2 m), the surface is exposed to convective heat transfer with an ambient temperature of 20°C. The convective heat transfer coefficient on the right side is assumed to be 200 W/m²K. Please answer the following questions: 1. What are the given material properties and boundary conditions? 2.
