17.66 One end of an insulated metal rod is maintained at 100°C, and the other end is maintained at 0°C by an ice-water mixture. The rod is 60cm long and has a cross-sectional area of 1.25cm2. The heat conducted by the rod melts 8.5g of ice in 10 minutes. Find the thermal conductivity k of the metal. Prepared by Vince Zaccone For Campus Learning Assistance Services at UCSB

More ice, from a refrigerator at -15°C, is added to the mixture in the bucket, and when thermal equilibrium has been reached, the total mass of ice in the bucket is 0.778kg. Assuming no heat is exchanged with the surroundings, what mass of ice was added? Prepared by Vince Zaccone For Campus Learning Assistance Services at UCSB
