Heat transport theories

Heat transport theories describe how thermal energy moves through materials. There are three main mechanisms: conduction, where heat flows through solids via particle collisions; convection, which involves fluid movement carrying heat (like boiling water); and radiation, where heat transfers through electromagnetic waves (like sunlight). These theories use physics principles to predict how quickly and efficiently heat spreads, depending on material properties, temperature differences, and environment. Understanding these processes helps in designing everything from insulation in buildings to cooling systems in electronics.
