1.	One end A of a metallic rod length 10 cm is inserted in a furnace whose temperature is 827∘C. The curved surface of the rod is insulated. The room temperature is 27∘C. When the steady state is attained, the temperature of the other end B of the rod is 702∘C. Find the thermal conductivity of the metal ( in SI units)Stefan's constant =5.67×10−8W m−2K−4.
Answer» One end A of a metallic rod length $10 cm$ is inserted in a furnace whose temperature is $827^{\circ} C$ . The curved surface of the rod is insulated. The room temperature is $27^{\circ} C$ . When the steady state is attained, the temperature of the other end B of the rod is $702^{\circ} C$ . Find the thermal conductivity of the metal $(in SI units)$ Stefan's constant $= 5.67 \times 10^{- 8} {W m}^{- 2} K^{- 4}$ .
