Steam is defined as what type of water?

Steam is defined as vaporized water. When water is heated to its boiling point, it undergoes a phase change from liquid to gas, resulting in steam. This gas can occur at various temperatures above the boiling point of water, but fundamentally, steam represents the gaseous state of water molecules that have transitioned from the liquid form due to the application of heat.

In the context of steam generation, it's important to note that the term encompasses not only the visible vapor that we see escaping from a kettle but also the invisible gas that exists in the air at higher temperatures. Understanding steam as vaporized water is crucial in various applications, such as in steam engines, heating systems, and cooking, where this gaseous form plays an essential role in energy transfer and processes.
