Lämmönjohtumisen
Lämmönjohtumisen refers to the process by which heat energy is transferred through a material or between objects in direct contact without the movement of the material itself. This transfer occurs at the molecular level, where vibrating atoms or molecules collide with their neighbors, passing on kinetic energy. The rate of heat conduction depends on the material's thermal conductivity, temperature difference, and the cross-sectional area through which heat is flowing.
Different materials conduct heat at varying efficiencies. Metals, such as copper and aluminum, are excellent thermal
The fundamental principle governing heat conduction is Fourier's Law, which mathematically describes the relationship between heat
