Wärmetransfer

Heat transfer is the movement of thermal energy from one system or object to another as a result of a temperature difference. It is a fundamental concept in physics and engineering, describing how heat moves through different mediums.

There are three primary modes of heat transfer: conduction, convection, and radiation. Conduction involves the transfer of heat through direct contact between particles, typically occurring in solids. Convection refers to the transfer of heat by the movement of fluids or gases, where warmer parts rise and cooler parts sink. Radiation is the transfer of heat through electromagnetic waves, which can occur even in a vacuum, as seen with the heat from the sun.

Heat transfer principles are applied in numerous technologies, including cooling systems, heating devices, and thermal insulation. Understanding and controlling heat transfer is crucial for optimizing energy efficiency and safety in various industrial and domestic applications.
