== Conduction ==
- Conduction can be defined as the heat transfer through a substance because of a temperature gradient. The rate of heat transfer by conduction between two regions of a substance is proportional to the temperature difference between them. The constant of propotionality is called thermal conductivity of the material.
- Mathematically, it can be described by using the Fourier's law:
k = Thermal conductivity of the material (W/m-K)
A = Cross-sectional area of the object parallel to heat conduction
T = Temparature (K)
X = Length of the object
