Gibbs Free Energy
Version 1.0.0 · Updated 2026-07-30
CORE DEFINITION
Under constant temperature and pressure, the energy available in a system to do useful work. Whether a process can occur spontaneously depends on the change in Gibbs free energy (ΔG). If ΔG < 0, the process is spontaneous; if ΔG > 0, energy input is required.
SCAFFOLDING EFFECT
Reduce cognitive load
An energy criterion for judging whether something can be accomplished. When driving change, calculate the system's ΔG (benefit minus entropy increase). If the result is negative, the change will proceed smoothly; if positive, you must continuously input significant external energy (strong will/funding) to maintain it, otherwise it will revert as soon as you let go.
Anchor fast decisions
ΔG = ΔH - TΔS, i.e., free energy change = enthalpy change (energy) minus temperature times entropy change (disorder cost). Systems spontaneously tend toward lower free energy states; if the target state has higher free energy, continuous energy input is required to maintain it, and it will revert once energy is removed. Applied to organizational/personal change: the 'spontaneity' of change depends on whether it reduces the system's total resistance (benefit minus friction); otherwise, it must be sustained by external will.
