energiaátvitelnek
Energiaátvitelnek refers to the process of transferring energy from one place to another. This can occur through various mechanisms, including conduction, convection, and radiation. Conduction is the transfer of heat through direct contact of particles. For example, when a metal spoon is placed in hot soup, the heat is conducted from the soup to the spoon. Convection is the transfer of heat through the movement of fluids, such as liquids or gases. This is observed when boiling water, where warmer, less dense water rises and cooler, denser water sinks, creating a circular motion. Radiation is the transfer of energy through electromagnetic waves, without the need for a medium. The most common example is the heat we feel from the sun.
In a broader sense, energiaátvitelnek can also describe the transmission of electrical energy through power lines
