A large concrete slab 1.0 m thick has one dimensional temperature distribution T = 4 - 10x + 20x2 + 10x3, where T is temperature and x is distance from one face towards other face of wall. If the slab material has thermal diffusivity of 2 × 10-3 m2/hr. What is the rate of change of temperature at the other face of the wall?
