Vapor pressure is a fundamental thermodynamic property that describes the equilibrium pressure exerted by a vapor just above its liquid (or solid) phase at a given temperature. It reflects the volatility of a substance and affects the evaporation rate of volatile components, particle formation and growth, chemical purity. Understanding vapor pressure is also essential in evaluating fuels and atmospheric pollutants. Despite technological progress, accurate measurement remains challenging and each method presents certain benefits and limitations.
This presentation will explore the principles underlying vapor pressure, the motivations behind its measurement, and the diverse techniques used to obtain reliable values. By understanding these aspects, scientists and engineers can employ the most appropriate method for their specific application.
