Thermal conductivity of wood depends on
A. Moisture
B. Density
C. Temperature
D. All of the above
Answer: Option D
Solution (By Examveda Team)
Thermal conductivity is a material property.It will not differ with the dimensions of a material, but it is dependent on the temperature, the density and the moisture content of the material.
The thermal conductivity of a material depends on its temperature, density and moisture content.
This Question Belongs to Mechanical Engineering >> Heat And Mass Transfer
Thermal conductivity (often expressed as k, λ, or κ) refers to the intrinsic ability of a material to transfer or conduct heat. It is one of the three methods of heat transfer, the other two being: convection and radiation. Heat transfer processes can be quantified in terms of the corresponding rate equations. The speed equation in this mode of heat transfer is based on Fourier's law of heat conduction.
