Soojusülekande
Soojusülekande refers to the transfer of thermal energy between objects or systems at different temperatures. This process naturally occurs from a region of higher temperature to a region of lower temperature and aims to reach thermal equilibrium. There are three primary mechanisms by which soojusülekande takes place: conduction, convection, and radiation.
Conduction is the transfer of heat through direct contact of particles. In solids, this happens via vibrations
Convection involves the transfer of heat through the movement of fluids (liquids or gases). When a fluid
Radiation is the transfer of heat through electromagnetic waves, such as infrared radiation. Unlike conduction and
Understanding soojusülekande is crucial in various fields, including thermodynamics, engineering, and everyday life, influencing the design
