Fázisátmenetének

Fázisátmenetének is a Hungarian term that translates to "phase transition" in English. It refers to the physical process where a substance changes from one state of matter to another. These transitions occur at specific temperatures and pressures. Common examples include melting (solid to liquid), freezing (liquid to solid), boiling (liquid to gas), condensation (gas to liquid), sublimation (solid to gas), and deposition (gas to solid). During a phase transition, the physical properties of the substance, such as density, viscosity, and heat capacity, change abruptly. The energy required to drive these transitions is known as latent heat. For instance, latent heat of fusion is absorbed during melting, and latent heat of vaporization is absorbed during boiling. These transitions are reversible, meaning a substance can change back to its original state under different conditions. The study of phase transitions is crucial in various scientific fields, including thermodynamics, materials science, and chemistry, as it helps understand the behavior of matter under different environmental conditions. The specific point at which a phase transition occurs can be influenced by external factors like pressure.
