Boiling point and Melting point-Physical Properties

Boiling point and Melting point--

The boiling point is the temperature at which a substance changes from a liquid into a gas.
The boiling point varies for different substances and can be used to help identify elements of the periodic table and other substances. For example, water and rubbing alcohol look similar but water has a boiling point of 212 f and 100 c and rubbing alcohol has a boiling point of 180.7 f and 82.6 c
The element found on the periodic table with the lowest boiling point is helium at -452.1 f and -269c
Tungsten has the highest boiling point at 10,030 f which is 5660 c

Boiling point varies with your elevation. It is higher at sea level and decreases as you gain elevation. As a result,

The standard boiling point has been defined by IUPAC since 1982 as the temperature at which boiling occurs under a pressure of 1 bar which is a fancy way of saying the standard boiling point is the boiling point at sea level

The melting point is the temperature at which a substance changes from a solid to a liquid.
This snow melting is an example of the water reaching it’s boiling point.
The melting point is also impacted by atmospheric pressure which changes with elevation but not as boiling point does.
The melting point is a physical property and can be used to identify substances.
The melting point of water is 32 f and 0 c
Helium has the lowest melting point at -272 c and carbon has the highest at 3500 c
Compare this to steel which has a melting point of 1510 degrees c
