Lammonsiirtoteoria, or heat transfer theory, is a fundamental branch of physics and engineering that deals with the study of thermal energy in motion. It explores how heat moves from one object or system to another, and the principles governing these processes. The theory primarily focuses on three distinct mechanisms of heat transfer: conduction, convection, and radiation.

Conduction is the transfer of heat through direct contact of particles. In solids, this occurs when vibrating atoms or molecules collide with their neighbors, passing on thermal energy. Liquids and gases also exhibit conduction, though it is generally less efficient than in solids. Convection involves the transfer of heat through the movement of fluids, such as liquids or gases. This can be natural, driven by density differences caused by temperature variations, or forced, where an external force like a fan or pump moves the fluid. Radiation is the transfer of heat through electromagnetic waves, requiring no medium and capable of traveling through a vacuum. All objects with a temperature above absolute zero emit thermal radiation.

Understanding lammonsiirtoteoria is crucial in numerous applications, including the design of heating and cooling systems, insulation materials, power generation, and the analysis of thermal behavior in various natural phenomena. Engineers and scientists use the principles of heat transfer theory to predict and control temperature changes in complex systems.
