Steam (clear), or water vapor (usually in the form of a whitish fog-like cloud or stream).
Water changes from a liquid to a gas in a process known as evaporation. (Think about a boiling pot of water on a stove).As the temperature rises, the water becomes water vapor, a gas.

When water evaporates it becomes a gas.
gas
It depends on what substance you a talking about. Water becomes a gas (boils) at 100oC.
This change is called liquefaction.
The water becomes a gas.
By evaporation water become a gas.
evaporation
That one is easy. It becomes a gas. That process is called "Vaporation". The steam that comes out of the water is the gas. It only becomes a gas when the water boils.
When water is in the form of a gas, it is called water vapour.
