One end of an iron rod 37 cm long and 3.5 cm in diameter is in ice water, the other in boiling water (the figure(Figure 1) ). The rod is well insulated so no heat is lost out the sides.

What is the heat-flow rate along the rod?

Express your answer using two significant figures. Can you please show me every single step..
