The temperature distribution in a large concrete slab in one dimension is T(x) = 4x³ + 3x² + 4x + 5, where T is temperature in °C and x is distance in meter from one face towards the other face of wall. Thickness of slab is 1 m. Thermal diffusivity of wall is 2 × 10^–3 m²/hr. What is the rate of change of temperature at the other face of wall?
