Two thermal energy reservoirs at temperatures of 27◦C and − 43◦C, respectively, are separated by a slab of material 10 cm thick and 930 cm 2 in cross-sectional area. The slab has a ther�mal conductivity of 0.14 W/m·K. The system is operating atsteady-state conditions. what are the rates of change of entropy of (a) the higher temperature reservoir, (b) the lower tempera�ture reservoir, (c) the slab, and (d) the whole universe as a result of this process? (e) Does your answer satisfy the Second Law of Thermodynamics?
