| 热焓 | rè hán | enthalpy; heat content (thermodynamics) | |
| 自由焓 | zì yóu hán | free enthalpy (thermodynamics); Gibbs free energy | |
| 显焓 | xiǎn hán | sensible enthalpy (thermodynamics); energy required to go from one state to another |
| 1 | Helmholtz free energy? Enthalpy? Which one? | |
| 2 | We can calculate our enthalpy of mixing. | |
| 3 | So there's no enthalpy of mixing. | |
| 4 | That's by definition of enthalpy. | |
| 5 | A molar enthalpy of or whatever, iron, as a solid at 298.15 Kelvin is zero. |
