There are many applications of heat conduction in our everyday lives. Heat conduction is the process where heat, or internal energy is transferred within a body or from one body to another due to the collisions of particles. These particles may include molecules, atoms, and electrons. One common example of heat conduction in our everyday lives is cooking. An iron skillet is placed on top of the stovetop. Heat will always flow from a region of higher concentrated energy to a region of lower concentrated energy. When the stovetop is turned on, there is a temperature difference between the iron skillet and the stovetop. However, this temperature difference decays over time and as a result, the thermal equilibrium is achieved. The heat transfer is in the direction of decreasing temperature, which in this case is from the stovetop to the bottom of the iron skillet.
