Phase Transition News

A phase transition refers to the change of a substance from one state of matter to another, such as from a solid to a liquid, liquid to gas, or solid to gas. These transitions occur when energy, typically in the form of heat, is added or removed from a system, causing changes in the arrangement and energy levels of the molecules within the substance. Common examples include the melting of ice into water, the boiling of water into steam, and the sublimation of dry ice into carbon dioxide gas. Phase transitions are characterized by specific changes in properties such as temperature, pressure, and volume, and are classified into different types, like first-order transitions which involve a latent heat (e.g., melting, boiling) and second-order transitions which do not (e.g., superconducting transitions). These phenomena are fundamental to various scientific fields, including physics, chemistry, and materials science.

Researchers Discover a New Form of Liquid

Scientists have discovered that “supercooled” water transforms into a new form of liquid, a “liquid-liquid” phase transition that is important for understanding basic processes during…
