Heat conduction is the process by which heat energy is transferred through materials. When one part of an object, like a metal rod, is heated, the particles in that area move faster and collide with neighboring particles. This transfer of energy continues along the rod, causing the entire object to warm up over time. This phenomenon is essential in everyday life. For example, when you touch a hot stove, heat conducts from the stove to your hand, which is why you feel the heat. Understanding heat conduction helps in designing better insulation for homes and improving cooking methods.
