일반물리학 1 — Temperature, Heat, and the First Law of Thermodynamics: Problem 43

43 A cylindrical copper rod of length $0.60\text{ m}$ and cross-sectional area $6.0\text{ cm}^2$ is insulated along its side. The ends are held at a temperature difference of $100^\circ\text{C}$ by having one end in a water–ice mixture and the other in a mixture of boiling water and steam. At what rate (a) is energy conducted by the rod and (b) does the ice melt?
