adiabatic limit

The adiabatic limit refers to a process where changes happen gradually enough that a system remains in near-equilibrium throughout. Imagine slowly turning a knob so that the system adjusts smoothly without sudden disturbances. In physics, it means parameters like temperature, pressure, or magnetic fields change slowly compared to the system's internal response time, allowing the system to adapt smoothly. This concept is important in areas like quantum mechanics, thermodynamics, and electromagnetism, ensuring that transitions are gentle enough to prevent the system from experiencing abrupt, non-reversible changes.
