Is water boiling at 100 degrees Celsius a physical change?
The boiling of water is indeed an example of physical change.
Changes of state, solid to liquid, liquid to gas, etc. are usually physical changes in that no new substances are formed, though the volume occupied by a given number of particles may vary markedly.

Certainly, the boiling point of water at 100 degrees Celsius is a physical transition from a liquid to a gas without changing the molecular makeup of the water.

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.
