1. Figure.1 depicts a plane wall of thickness L = 0.2 m experiences uniform volumetric heating at a rate q. One surface of the wall (x = 0) is insulated, and the other surface is exposed to a fluid at T = 25°C, with convection heat transfer characterized by h = 1200 Initially, the temperature distribution in the wall is T(x, 0) = a + bx², where a = 300 °C, b = -1.0 × 10-4, and x is in meters. W m2.K Suddenly, the volumetric heat generation is deactivated (q=0 for t≥0), while convection heat transfer continues to occur at x = L. The properties of the wall are = 5000 kg/m3, cp=500, and k = 100- kg.K' W m.K ,k,p, cp, q(t≤ 0)
