The boiling temperature at 1 atm.pressure is called as the normal boiling point while the boiling point at 1 bar is called the standard boiling point. The normal boiling point of water is 100° C and the standard boiling point in 99.6° C.
The pressure directly affects the boiling point. In hilly areas liquids boil at the lower temperature as compared to plains. The reason for this is that at higher altitudes the pressure is very low, hence the boiling point is also comparatively low.
The boiling point is not a result of heating, rather it is the outcome of the increasing vapor pressure. Initially, we can see a line between the liquid phase and vapor phase but as the temperature increases, the speed of vaporization also increases leading to more and more molecules entering the vapor phase. With the rising density of vapors, the density of liquids decreases making the molecules move apart from each other.
