lämpövaihdon
Lämpövaihto, often translated as heat transfer, is the process by which thermal energy is exchanged between systems due to a temperature difference. This fundamental principle of physics governs how heat moves from hotter regions to colder regions. There are three primary mechanisms through which lämpövaihto occurs: conduction, convection, and radiation.
Conduction is the transfer of heat through direct contact between particles. In solids, heat energy causes
Convection involves the transfer of heat through the movement of fluids, which can be liquids or gases.
Radiation is the transfer of heat through electromagnetic waves, most notably infrared radiation. Unlike conduction and
