Explain the following in reference to thermal conduction in a rod: Isothermal surface

The thermal conductivity of a rod depends on

In the following solids thermal conductivity is maximum for .

What do you mean by variable state and steady state in thermal conduction ? Define temperature gradient

An irregular rod of same uniform material as shown in figure is conducting heat at a steady rate. The temperature gradient at various sections versus area of cross section graph will be

A uniform rod of thermal conductivity of 65J//m-s-^(@)C is surrounded by an insulator on its sides. One of its ends is put in a furnace, while the other end is kept exposed. If the temperature gradient of the rod is -75^@C//m , find the emissive power of the exposed end.

According to the experiment of Ingen Hausz the relation between the thermal conductivity of a metal rod is K and the length of the rod whenever the wax melts is
