The process of conduction in metals is important for engineers to understand when preparing to pass the PE Mechanical exam. The law of heat conduction, or Fourier's law, states that the time rate of the heat transfer through the material is proportional to the negative gradient in the temperature and to the area.

What is the importance of conduction?

Conduction in the Atmosphere

Conduction, radiation and convection all play a role in moving heat between Earth's surface and the atmosphere. Since air is a poor conductor, most energy transfer by conduction occurs right near Earth's surface.

What are 3 examples of conduction?

Conduction: Touching a stove and being burned. Ice cooling down your hand. Boiling water by thrusting a red-hot piece of iron into it.
