fázisátalakulásnak

Fázisátalakulás refers to a change in the physical state of a substance. This occurs when a material transitions from one phase to another, such as solid to liquid, liquid to gas, or vice versa. Common examples include melting, freezing, boiling, condensation, sublimation, and deposition. These transformations are driven by changes in temperature and pressure, which affect the kinetic energy of the molecules within the substance and the forces holding them together.

During a phase transition, the substance typically absorbs or releases energy. For instance, melting requires energy input (latent heat of fusion) to overcome the intermolecular forces in the solid state, while freezing releases this energy. Similarly, boiling requires energy input (latent heat of vaporization) to transition from liquid to gas, and condensation releases this energy. The specific temperatures and pressures at which these transitions occur are characteristic properties of each substance. Understanding fázisátalakulás is crucial in various scientific and engineering fields, including thermodynamics, materials science, and meteorology, as it influences the behavior and applications of matter.
