A, B, and C are three identical conductors made from different materials. They are kept in contact as shown. Their thermal conductivities are $K$, $2K$, and $\frac{K}{2}$. The free end of A is at $100^\circ C$ and the free end of C is at $0^\circ C$. During steady state, the temperature of the junction of A and B is nearly... $^\circ C$.

Question

A, B, and C are three identical conductors made from different materials. They are kept in contact as shown.

Their thermal conductivities are $K$, $2K$, and $\frac{K}{2}$. The free end of A is at $100^\circ C$ and the free end of C is at $0^\circ C$. During steady state, the temperature of the junction of A and B is nearly... $^\circ C$.
