Question
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 L2 of steel (one end in the ice-water mixture). Both sections of the rod
have cross-sectional areas of 4.00 cm?. 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 L2 of the steel section?
