The heat transfer coefficient of superheated steam is poor. Saturated steam has a better heat transfer coefficient, and also most of the heat transferred from steam occurs because of the condensation phase change.
Water as steam racing towards the surface
The geyser occurs when pressure builds up underground and forces a blast of steam and water
Steam is produced whenever water boils, which occurs at 100 degrees Celsius at standard pressure and temperature (boiling point changes at altitudes because of the pressure change, remember).
A good example of a simple Physical Change occurs in a tea pot. The hot, liquid water boils and goes off as steam. Steam is still water (no chemical change,) but is now a gas.
Energy transformation in a steam iron occurs when electrical energy is converted to thermal energy in the heating element. This thermal energy is then transferred to the water in the iron's reservoir, causing it to evaporate and turn into steam. The steam, in turn, transfers heat energy to the fabric being ironed, enabling the smoothing process.
Actually steam is water. Just tiny tiny droplets of water. But the answer I think you're looking for is condensation which is the process of water vapor (not steam) which is a gas cools down and condenses into water.
When water turns to steam, it is called evaporation. This occurs when water reaches its boiling point and changes from a liquid to a gas.
The process of steam turning into ice is called deposition. It occurs when water vapor cools down and changes directly into solid ice without passing through the liquid state.
In a steam engine, energy transfer occurs from the burning fuel (such as coal or wood) to water, which boils and turns into steam. The high-pressure steam then transfers its energy to the engine's pistons, causing them to move and power the machinery. Finally, the steam releases its energy to the surrounding environment as it cools back down to water, completing the cycle.
