Question

The coefficient of thermal conductivity depends upon?

Answer 1

Coefficient of Thermal conductivity :

1. Thermal conductivity is the property by which a substance allows free and easy passage for heat.
2. $\mathrm{k}$ is defined as the Coefficient of Thermal conductivity in the ratio of watts per meter Kelvin.

Coefficient of Thermal conductivity dependence :

1. Thermal conductivity which is the measure of the heat transfer ability of a material depends on temperature.
2. The coefficient of thermal conductivity depended upon Temperature.
3. It also depends upon the Physical properties of the material such as the nature of the material.
4. Water content also affects the coefficient of thermal conductivity.
5. The pressure of material changes the coefficient of thermal conductivity.
6. The coefficient of thermal conductivity is independent of dimensions, temperatures, and other external factors.
7. Coefficient of Thermal Conductivity is the internal property of the metal and is independent of all the external properties of the material.

Hence The coefficient of thermal conductivity depends upon temperature, physical properties of the material, water content, and the pressure on the material.
