VAPOUR PRESSURE Meaning and
Definition
-
Vapour pressure is a term that describes the pressure exerted by the molecules of a substance in its gaseous state when it is in equilibrium with its liquid or solid phase at a given temperature. It is a measure of the tendency of a substance's molecules to escape from the liquid or solid phase and enter the gaseous phase.
Vapour pressure is influenced by various factors, but temperature is the most crucial one. As the temperature of a substance increases, its vapour pressure also increases, as more molecules gain enough kinetic energy to transition into the gaseous phase.
Vapour pressure is an important characteristic of volatile substances, as it determines their ability to evaporate into the atmosphere. A higher vapour pressure indicates a greater evaporation rate, while a lower vapour pressure indicates a slower rate of evaporation.
In practical terms, the concept of vapour pressure is widely used in various applications, such as in the fields of chemical engineering, pharmacology, and meteorology. It helps in understanding the behaviour of substances in different conditions, like determining the boiling point of a liquid, predicting the effects of temperature on the release of drugs from medication patches, or analyzing the formation of clouds and precipitation in the atmosphere.
Overall, vapour pressure plays a vital role in elucidating the relationship between the gaseous, liquid, and solid phases of a substance and provides valuable information about its properties and behaviour under specific conditions.

Etymology of VAPOUR PRESSURE
The word "vapour pressure" is derived from two different sources.
The term "vapour" comes from the Latin word "vapor", meaning "steam" or "vapor". It is related to the verb "vapōrāre", which means "to emit steam or vaporize". This Latin word has been adopted in various languages in its original form or slight variations to refer to the gaseous state of substances.
The term "pressure" comes from the Latin word "pressūra", which means "act of pressing" or "force exerted". It is derived from the verb "premere", meaning "to press". The word "pressure" is commonly used in physics and chemistry to denote the force or exertion applied to a surface or a substance.
