fázisátalakulásra

Fázisátalakulás is a Hungarian term that translates to "phase transition" in English. It refers to a physical process where a substance changes from one state of matter (phase) to another. These transitions occur at specific temperatures and pressures and are driven by changes in energy. Common examples include melting, freezing, boiling, and condensation.

Melting is the transition from solid to liquid, occurring at the melting point. Freezing is the reverse process, from liquid to solid, happening at the freezing point, which is the same temperature as the melting point. Boiling is the transition from liquid to gas, taking place at the boiling point, while condensation is the change from gas to liquid. Sublimation is a less common transition where a substance changes directly from solid to gas, bypassing the liquid phase, and deposition is the reverse, from gas to solid.

These phase transitions involve the absorption or release of energy, known as latent heat. For instance, energy must be absorbed for a solid to melt into a liquid, and energy is released when a liquid freezes into a solid. Understanding fázisátalakulás is crucial in various scientific and engineering fields, including thermodynamics, materials science, and meteorology. It explains phenomena like the formation of ice, the generation of steam, and the behavior of matter under different environmental conditions.
