soojakadusid
Soojakadusid, which translates to "heat loss" in English, refers to the unwanted dissipation of thermal energy from a warmer system to its colder surroundings. This phenomenon is a fundamental aspect of thermodynamics and occurs through three primary mechanisms: conduction, convection, and radiation. Conduction involves heat transfer through direct contact of molecules, moving from areas of higher temperature to lower temperature within a substance or between substances in contact. Convection is the transfer of heat through the movement of fluids, such as air or water, where warmer, less dense portions rise and cooler, denser portions sink, creating currents that carry thermal energy. Radiation is the transfer of heat through electromagnetic waves, which can travel through a vacuum and does not require a medium.
In buildings, soojakadusid is a significant concern for energy efficiency. Heat can escape through walls, roofs,
