A long rod, insulated to prevent heat loss along its sides, is in perfect thermal contact with boiling water (at atmospheric pressure) at one end and with an ice-water mixture at the other ( Fig. E17.62 ). The rod consists of a 1.00-m section of copper (one end in boiling water) joined end to end to a length L 2 of steel (one end in the ice-water mixture). Both sections of the rod have cross-sectional areas of 4.00 cm 2 . The temperature of the copper-steel junction is 65.0°C after a steady state has been set up. (a) How much heat per second flows from the boiling water to the ice-water mixture? (b) What is the length L 2 of the steel section? Figure E17.62

A heat conducting rod, 0.90 m long, is made of an aluminum section that is 0.10
m long, and a copper section that is 0.80 m long. Both sections have cross-
sectional areas of 0.00040 m2 .The aluminum end is maintained at a temperature
of 40° C and the copper end is at 150° C. The thermal conductivity of aluminum
is 205 W/m · K and of copper is 385 W/m · K. Steady state has been reached, and
no heat is lost through the well-insulated sides of the rod. The temperature of the
aluminum-copper junction in the rod is closest to
A wooden ice box has a total area of 1.50 m2 amd walls with an average thickness of 2.0 cm. The box contains ice at 0.0 oC. The inside of the box is kept cold by melting ice. How much ice melts in one day if the ice box is kept in the shade of tree at 29 oC. (Assume the thermal conductivity of wood is 0.16 kJ/s m oC)
