Pvap

Pvap is a term used in several fields, and there is no single, universally accepted definition. In science and engineering, Pvap is commonly used informally to denote vapor pressure—the equilibrium pressure exerted by a vapor in contact with its condensed phase. In practice, P_vap or Pvap can appear in notes, datasets, or simplified equations to indicate the vapor pressure of a substance at a given temperature. This property is central to understanding volatility, boiling behavior, and evaporation rates, and it features in thermodynamics, physical chemistry, and meteorology when modeling humidity and phase changes.

Beyond chemistry, Pvap may be encountered as an acronym or project name in various organizations or software initiatives. Because these uses are context-specific, they do not share a standard expansion across domains. When encountering Pvap, it is important to consult the surrounding text, glossary, or metadata to determine its intended meaning.

In most technical contexts, distinguishing Pvap as vapor pressure from other uses relies on capitalization, domain, and accompanying terms such as temperature, pressure, or phase. If an explicit expansion is needed, sources will usually provide it.
