Heat Flowing through a Sectioned Rod
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. The rod consists of a 1.00 m section of copper (with one end in the boiling water) joined end-to-end to a length L2 of steel (with one end in the ice water). Both sections of the rod have cross-sectional areas of 4.00 cm2. The temperature of the copper-steel junction...

A heat conducting rod, 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 0,0004 m2. The aluminum end is maintained at a temperature of 20°C and the copper end is at 121°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....

Ice and COPPER STEEL water water A copper rod and a steel rod are joined to- gether as shown. Both have a cross sectional area of 4.0cm2. Both rods are insulated so that heat can be conducted only along their length. One end of the copper rod is immersed in boil- ing water, and one end of the steel rod is im- 65.0°C mersed in a mixture of ice and water 0°C. The temperature at the junction point is stable...

Two square wires are composed differently, see the figure of their cross-sections. Wire 1 is a square wire of material A but with a circular center of material C. The diameter of the circular inside is equal to the length of side of the square. The second square wire has the same cross-sectional area as the first but is entirely comprised of material A. Both wires are the same length and setup to have the same temperature difference maintained between...
