In this regard, what is the normal boiling point of a liquid?
The boiling point of a liquid varies according to the applied pressure; the normal boiling point is the temperature at which the vapour pressure is equal to the standard sea-level atmospheric pressure (760 mm [29.92 inches] of mercury). At sea level, water boils at 100° C (212° F).
Likewise, why is boiling point important? The boiling point of organic compounds can give important information about their physical properties and structural characteristics. Boiling point helps identify and characterise a compound. A liquid at a higher pressure has a higher boiling point than when that liquid is at lower atmospheric pressure.
Simply so, what happens to liquid at boiling point?
Boiling is the process by which a liquid turns into a vapor when it is heated to its boiling point. The change from a liquid phase to a gaseous phase occurs when the vapor pressure of the liquid is equal to the atmospheric pressure exerted on the liquid.
Is boiling point a physical property?
Physical properties are properties that can be measured or observed without changing the chemical nature of the substance. Some examples of physical properties are: boiling point (intensive): the temperature at which a substance boils. melting point (intensive): the temperature at which a substance melts.
