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 thermal conductivity of the material and the temperature difference between them.
  • Mathematically, it can be described by using the Fourier's law:

Q_{Conduction} = -k\Delta T
