Physics · Class 11 · CBSE — Thermal Properties of Matter
Two bars of same length and same cross-sectional area but of different thermal conductivities K1 and K2 are joined end to end as shown in the figure. One end of the compound bar is at temperature T1 and the opposite end at temperature T2 (where T1 > T2). The temperature of the junction is
\(\begin{array}{|l|l|} \hline T_{1} \\ \hline K_{1} & K_{2} \\ \hline \end{array}\)
\(\begin{array}{|l|l|} \hline T_{1} \\ \hline K_{1} & K_{2} \\ \hline \end{array}\)
