The thermal conductivity of aluminumomnp+c 7: aj1b2wcws1zpj4zuoeb0darv9 d9y-+ v x9lk7b ;e 7 is twice that of brass. 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 radiyu9- d9x7+z pj9dzevk0bab;v47or l ei. 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. $155 \; ^{\circ}C$
