G The rods are pressed against each other. Each of the rods has a length of 20 cm and a diameter of 2 cm. The temperatures at the two outer ends of the rods are maintained at T1=100 °C and T3=60 °C, respectively. The temperature at the interface is T2=85 °C. The thermal conductivity of the rod A is 105 W/(m∙K). Determine the thermal conductivity of the rod B. [16 pts]

In a unit cell of fcc structure, indicate the position of one of the tetrahedral interstitial sites by plotting the corresponding tetrahedron. do the same for one of the octahedral interstitial sites (in a separate fcc unit cell). mark the positions of all the tetrahedral and octahedral interstitial sites in the unit cells. how many equivalent tetrahedral sites and how many equivalent octahedral sites are contained in a fcc unit cell, respectively. what is the coordination number for a tetrahedral site and what is the coordination number for an octahedral site?
