dissipációról

Disszipáció refers to the irreversible dissipation of energy in a system, typically as heat, due to processes like friction, viscosity, or electrical resistance. This energy is lost from the organized, usable form and becomes randomized, increasing the entropy of the system. In physics, dissipation is a fundamental concept that explains why perpetual motion machines are impossible and why real-world systems tend towards equilibrium. For instance, when a fluid flows, viscosity causes internal friction, converting kinetic energy into heat, which then dissipates into the surroundings. Similarly, in electrical circuits, resistance leads to energy loss as heat generated by the flow of electrons. Understanding dissipation is crucial in fields ranging from thermodynamics and fluid mechanics to materials science and engineering, as it impacts efficiency, energy transfer, and the long-term behavior of physical systems. It's a key factor in why objects eventually stop moving when left to their own devices and why heat naturally flows from hotter to colder regions.
