JEE PHYSICS MCQ: THERMAL PROPERTIES OF MATTER

Heat is flowing through a rod of length $25.0 \mathrm{~cm}$ having cross-sectional area $8.80 \mathrm{~cm}^2$. The coefficient of thermal conductivity for the material of the rod is $K=9.2 \times 10^{-2} \mathrm{~kcal} \mathrm{~s}^{-1} \mathrm{~m}^{-1}{ }^{\circ} \mathrm{C}^{-1}$. The temperatures of the ends of the rod are $125^{\circ} \mathrm{C}$ and $0^{\circ} \mathrm{C}$ in the steady state. Calculate temperature of a point at a distance of $10.0 \mathrm{~cm}$ from the hot end.
