A long rod is insulated to prevent heat loss through its side. The rod connects a reservoir of boiling water at one end, and a reservoir containing an ice-water mixture at the other. The rod consists of a 1 m section of copper (with one end in the boiling water) joinded end-to-end to an unknown length of steel iron (with one end in the ice water). Both sections of the rod have a diameter of 2.25 cm. Once study state is achieved (i.e once the temperature along the road stops changing), the temperature of the copper-steel junction is 65C. Insulation 65.0C Boiling water COPPER 1.00 m STEEL Ice and water What is the length of the steel portion of the road? (Hint: What must be true about the rate of hate flow through each part of the rod?)
