1. Two long rods of the same diameter-one made of brass (k=85w/m.k) and
the other made of copper (k=375 w/m.k) have one of their ends inserted
into a furnace (as shown in the following figure). Both rods are exposed to
the same environment. At a distance of 105 mm from the furnace, the
temperature of the brass rod is 120°C. At what distance from the furnace
will the same temperature be reached in the copper rod?
