Vapor is a noun that refers to a gaseous state of a substance, typically corresponding to its liquid or solid state at a higher temperature. It is characterized by individual molecules or particles suspended in the air, occupying a larger space and having increased kinetic energy compared to a liquid or solid.
Vaporization, or the transformation from a liquid or solid into vapor, occurs when the substance is heated to a sufficiently high temperature, causing the particles to gain energy and become more mobile. This process breaks the intermolecular bonds, allowing the substance to transition into a gas.
Vapor is commonly observed in everyday life, such as seeing steam rising from a boiling pot of water or mist forming when warm air comes into contact with colder surfaces. It is important to note that vapor and steam are often used interchangeably, but steam specifically refers to water vapor.
In science and technology, the term vapor is frequently used within various fields. For example, in chemical processes, the control and manipulation of vapor is crucial, as it can influence reactions, transport of substances, and the creation of desired products. Furthermore, in industries like power generation, vapor is utilized to produce steam for powering turbines and generating electricity.
In summary, vapor denotes the gaseous form of a substance resulting from vaporization, characterized by its increased kinetic energy and individual molecules or particles suspended in the air.

The word "vapor" derives from the Latin term "vapor", meaning "steam, heat, vapor", which originally comes from the verb "vapōrāre", meaning "to emit vapor", "to exhale steam". This Latin verb is believed to be derived from the Proto-Indo-European root word "*wegw-", meaning "to weave, to move to and fro", which is also where words like "wave" and "vibrate" originate from. The word "vapor" has been in use in English since the 14th century.
