   | Process Type | Associated Energy Difference | Typical Units | Implication |
   | :--- | :--- | :--- | :--- |
   | Electronic Excitation | $\Delta E$ (Photon Energy) | Joules, electron-volts ($\text{eV}$) | Absorption or emission of specific wavelengths. |
   | Phase Change | $\Delta H$ (Enthalpy of Transition) | $\text{kJ/mol}$ | Energy barrier for structural rearrangement (e.g., melting). |
   | Chemical Reaction | $\Delta G$ (Gibbs Free Energy) | $\text{kJ/mol}$ | Spontaneity and [equilibrium position](/entries…
