You think to vapours of a liquid.
They are the same thing. Most commonly the term melting point is used to describe the temperature at which a substance first co-exists in both a liquid and solid state. Freezing point is used usually to describe a substance that is usually liquid at room temperature, such as water. Conversely the term 'boiling point' refers to the first temperature at which the substance exists in both liquid and gaseous states.
boiling point
earth is the only planet where the same substance can exist in gaseous , liquid , and solid form
From solid to liquid, from liquid to gaseous, from gaseous to liquid, from liquid to solid, and in sublimation from solid to gaseous or the reverse, chemical properties do not change.
We know that for any given substance, and at a given pressure, the gas phase exists at a higher temperature than the liquid phase, which exists at a higher temperature than the solid phase. And temperature measures heat energy per molecule or atom, hence, gas particles have more energy than particles of the same substance in their liquid or solid phase.
when a substance exists as a liquid or solid under ordinary conditions its gaseous phase is called a vapor
water is the substance
If a substance that exists in liquid state was not in liquid state then it was in its other states of matter namely solid, gaseous.
Yes, all of them.

The boiling point of a substance is the temperature at which it changes from liquid state to gaseous or vapor state.
The temperature AND pressure at which the solid, liquid, and gaseous state can all coexist.
boiling point
... the substance can exist in the solid, liquid, and gaseous phases all at the same time.
vapor describes the gaseous state of substance that is generally a liquid or solid at room temperature as in water vapor.
Every substance has their own boiling point.
Yes, nitrogen exists in a gaseous form (N2) at at temperatures above its boiling point. It can also exist as a liquid at 77 K.
