Dynamic Equilibrium
Captions available
The idea
Dynamic equilibrium is the state a diffusing substance reaches once its gradient disappears, molecules still moving but with no net movement in any direction.
In practice
In a school chemistry lab, dye stirred into water spreads until color is uniform, though dye molecules keep drifting throughout the liquid.
Where people slip
Equilibrium here is dynamic, not static — molecular motion never stops, only the net direction does.
