lämpösiirron
Lämpösiirto refers to the transfer of thermal energy between physical systems. This process occurs when there is a temperature difference between the systems. Heat naturally flows from regions of higher temperature to regions of lower temperature. There are three primary mechanisms by which lämpösiirto takes place: conduction, convection, and radiation.
Conduction is the transfer of heat through direct contact. In solids, this happens as vibrations of atoms
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, such as infrared radiation. Unlike conduction and
