Conduction is the process by which heat or electricity is transferred through a material without any movement of the material itself. This occurs when particles in a solid, such as metals, vibrate and collide with neighboring particles, passing on energy. For example, when one end of a metal rod is heated, the heat travels to the cooler end through these particle interactions.
In conduction, the efficiency of heat transfer depends on the material's properties. Conductors, like copper and aluminum, allow heat to flow easily, while insulators, such as rubber and wood, resist heat transfer. This principle is essential in various applications, including cooking and electrical wiring.
