Physics - Heat & Thermo Question with Solution | TestHub

Three bars of the same area and length are joined in series with conductivities $K$, $3K$ and $2K$ in that order. The free end of the first is at $150^{\circ }$C and the free end of the last is at $30^{\circ }$C. Find the temperature ${\theta }_2$ at the junction between the second and the third bar in ${}^{\circ }$C (two decimals).
