The temperature distribution in a certain plane wall is: T-Ty =C₁+Cx²+C₁x² Where TI and T2 are the temperatures on each side of the wall. If the thermal conductivity of the wall is constant and the wall thickness is L, derive an expression for the heat generation per unit volume as a function of x, the distance from the plane where T-T1. Let the heat- generation rate be 'q0 at x = 0
