The answer to your question is Chemical change.

Explanation:

A Physical change is when matter changes its physical state, like evaporation, fusion, and solidification.

A Chemical change is when matter combines to form new substances.

In this problem, oxygen reacts with hydrogen to form a new substance (water) so oxygen undergoes a chemical change.
