Is boiling point considered a physical or chemical change?

The transition from liquid to gas is certainly an example of physical change.


Physical changes are largely changes of state: #"solid "rarr" liquid"#; #"solid "rarr " gas"#; #"liquid "rarr" gas"#. And of course the reverse processes, #"depositon, condensation"# also lie under this umbrella.

When something is boiling, its phase changes from the liquid phase to the gas phase; no chemical bonds are broken; molecules become farther removed from each other; and the transition qualifies as a physical change.
