Example: At higher elevations, such as hills and mountains, the atmospheric pressure is lower than one atmosphere, so water boils at a lower temperature than the normal boiling point. Molecule Types: Types of molecules in the liquid affect the boiling point of the liquid. read more
Essentially, the boiling point of water depends on two factors: atmospheric pressure and the amount of impurities present in the water. Boiling Point of Water at 1 Atmosphere Pressure can be measured in atmospheres; 1 atmosphere is the standard atmospheric pressure at sea level. read more
Factors That Affect the Boiling Point. Pressure: when the external pressure is: less than one atmosphere, the boiling point of the liquid is lower than its normal boiling point. equal to one atmosphere, the boiling point of a liquid is called the normal boiling point. read more
The boiling point of a liquid is the temperature at which it turns to vapor. Liquids turn to vapor when their vapor pressure equals the pressure of the surrounding air. A liquid’s vapor pressure is the pressure exerted by a liquid when its liquid and gaseous states have reached equilibrium. read more
