Steam is defined as?

Steam is defined as vaporized water, which means it is the gaseous state of water that occurs when water is heated to its boiling point, transitioning from a liquid to a vapor. This definition encapsulates the fundamental nature of steam, highlighting its formation from liquid water as it absorbs heat during the heating process.

When water reaches the boiling point, the molecules gain enough energy to break free from the liquid phase, resulting in steam. This steam can be utilized in various applications, such as in industrial processes, heating systems, and energy generation to harness its energy and thermal properties.

Other options, while related to the properties of water, do not accurately describe steam. For instance, superheated water refers to water that has been heated beyond its boiling point without actually transitioning to steam, which is a specific condition rather than a general definition. Supersaturated water is a term used in the context of solutions and refers to a state where the concentration of a solute exceeds the solubility, not applicable to describing steam. Moisture in the air pertains to the presence of water vapor within the atmosphere, but it is not a direct definition of steam itself. Thus, recognizing steam accurately as vaporized water is essential in understanding its role and behavior in various
