A brass rod, 75.0 cm long and having a cross-sectional area of 2.50 cm2, conducts heat from a large furnace at 375°C into a very large cold water bath at 10.0°C
without losing any heat at the lateral surface of the rod. Steady state has been established, and the thermal conductivity of brass is 109 W/m?K. The rate at which the entropy of the system (furnace plus water) is changing is closest to
A) 2.05 × 10-2 W/K.
B) 2.64 × 10-2 W/K.
C) 3.54 × 10-2 W/K.
D) 4.69 × 10-2 W/K.
E) 6.74 × 10-2 W/K.
