How many types of steam exist?

When we heat water, it starts to evaporate. At first, it evaporates only from the surface, and when it reaches the boiling point, it evaporates from its entire volume. The water changes from a liquid to the gaseous state called steam. At some point, an equilibrium is established. As many molecules evaporate from the water as condense back into it. The steam thus obtained is called saturated steam. It is used to conduct heat and in many other applications. The higher the pressure in the boiler, the higher the temperature of the steam, and the more energy it will contain per kilogram of steam. By changing the pressure of saturated steam, its temperature also changes.
