Even at room temperature, vapor pressure exists above a body of water. This means that some of the water particles with enough energy are removed from the body to the air.

1) Is this phenomenon called "evaporation"?
2) When we boil water, liquid water particles become "gas" water particles. Do we also consider the evaporated water particles "gas" particles?

Wikipedia is a pretty good resource. It's usually a good idea to try to find answers on your own, that way you can learn what you'd like right away:

Evaporation is a type of vaporization of a liquid, that occurs only on the surface of a liquid. The other type of vaporization is boiling, that instead occurs on the entire mass of the liquid. Evaporation is also part of the water cycle.
Evaporation is a type of phase transition; it is the process by which molecules in a liquid state (e.g. water) spontaneously become gaseous (e.g. water vapor). Generally, evaporation can be seen by the gradual disappearance of a liquid from a substance when exposed to a significant volume of gas. Vaporization and evaporation however, are not entirely the same processes. [citation needed]
