The thermal conductivity of aluminum is twice .q-p o(t 2vk(rd;qma pi 6kar:that of brass.v9mo18so2hbp66 iidro;47n .pud nus Two rods (one aluminum and the other brass) are joined together end to end in excellent thermal contact. The rods are of equal lengths and d9v1u 6 o4onri8p;d2pmshu n.io7s6b radii. The free end of the brass rod is maintained at $0 \; ^{\circ}C$ and the aluminum's free end is heated to $200 \; ^{\circ}C$. If no heat escapes from the sides of the rods, what is the temperature at the interface between the two metals?
A. $76 \; ^{\circ}C$
B. $133 \; ^{\circ}C$
C. $148 \; ^{\circ}C$
D. $155 \; ^{\circ}C$
