Thermal Conductivity

Statement I: Two solid cylindrical rods of identical size and different thermal conductivity K_1 and K_2 are connected in series. Then the equivalent thermal conductivity of two rods system is less than that value of thermal conductivity of either rod. Statement II: For two cylindrical rods of identical size and different thermal conductivity K_1 and K_2 connected in series, the equivalent thermal conductivity K is given by (2)/(K)=(1)/(K_1)+(1)/(K_2)

In the Ingen hausz method to compare the thermal conductivities of differnet substances the length upto which wax melted in copper and zinc rods are 9.3 cm and 5cm respectively Compare their thermal conductivities .
