GasFlüssigkeitswechsel
GasFlüssigkeitswechsel, often abbreviated as GFW, refers to a phase transition process where a substance changes from a gaseous state to a liquid state, or vice versa. This phenomenon is a fundamental concept in thermodynamics and chemistry, driven by changes in temperature and pressure. The specific conditions required for a GasFlüssigkeitswechsel to occur are determined by the substance's phase diagram, which illustrates the different phases a substance can exist in under various conditions.
When a gas cools down or its pressure increases, its molecules lose kinetic energy or are forced
