jämviktsdensitet
Jämviktsdensitet refers to the density of a substance or mixture when it is in a state of thermodynamic equilibrium. This equilibrium is typically reached under specific conditions of temperature and pressure. For a pure substance, the jämviktsdensitet is a unique value at a given temperature and pressure, reflecting the average mass per unit volume of its particles (atoms or molecules) arranged in their most stable configuration under those conditions.
In mixtures, jämviktsdensitet can be more complex. It depends not only on the temperature and pressure but
