Is boiling point considered a physical or chemical change?

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

Explanation:

Physical changes are largely changes of state: solid liquid; solid gas; liquid 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.
