As the temperature increases and the water approaches its boiling condition, some molecules attain enough kinetic energy to reach velocities that allow them to momentarily escape from the liquid into the space above the surface, before falling back into the liquid.
Further heating causes greater excitation and the number of molecules with enough energy to leave the liquid increases. As the water is heated to its boiling point, bubbles of steam form within it and rise to break through the surface.
Considering the molecular structure of liquids and vapours, it is logical that the density of steam is much less than that of water, because the steam molecules are further apart from one another. The space immediately above the water surface thus becomes filled with less dense steam molecules.
When the number of molecules leaving the liquid surface is more than those re-entering, the water freely evaporates. At this point it has reached boiling point or its saturation temperature, as it is saturated with heat energy.
Basically steam is invisible. What your seeing is not steam. Its the point at which the warm air (from the kettle) meets the cold air.
steam, which is a water form of a gas
Superheated steam is steam at a temperature higher than water's boiling point
Water.
no
when the water is heated at 100 c it becomes steam. because the boiling point of water is 100 c.
The boiling point. (99.97 degrees Celsius)
Steam
Steam is the gaseous form of water above its boiling point. When you see 'steam', that is not really steam, it's warm-water droplets in the air.
Steam is a gas stage of water. You can produce steam by heating water to boiling point.

The boiling point of water is 100 degrees celsius. The water will evaporate at boiling point. By the way what do you mean "what happens to the temperature of boiling water" if you think about it, it does not make sense.
No, it turns into steam. Water turns into ice at its freezing point.
At the boiling point, 100° C
It is called boiling point.

Superheated steam is steam at a temperature higher than water's boiling point
It will be the boiling point of water: 100oC
