Is boiling point considered a physical or chemical change?

Answer 1

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.

Because boiling point refers to a substance's transition from a liquid to a gas without changing its chemical makeup, it is regarded as a physical change.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
