A 30-cm bar is made from putting together three 10-cm bars of steel, copper, and aluminium, each having cross-sectional area 4cm2. One end of the steel is in contact with a nice-water mixture. When the system comes into equilibrium,

a) What is the temperature at the end of each bar, and

b) At what rate is ice melting?

c) What is the effective thermal conductivity of the 3-barcombination?

d) Would your answers go up, go down, or stay the same if the order were changed to copper-steel-aluminium? (Do NOT solve the problem again to answer this question.) Describe.
