Three slabs are joined together as shown in the figure. There is no thermal contact resistance at interfaces. The center slab experiences a non-uniform internal heat generation with an average value equal to 10000 Wm^-3, while the left and right slabs have no internal heat generation. All slabs have thickness equal to 1 m and thermal conductivity of each slab is equal to 5
Wm^-1K^-1. The two extreme faces are exposed to fluid with heat transfer coefficient 100 Wm^-2K^-1 and bulk temperature 30^oC as shown. The heat transfer in the slabs is assumed to be one dimensional and steady, and all properties are constant. If the left extreme face temperature T₁ is measured to be 100^oC, the right extreme face temperature T₂ is ___________^oC.
