What is a physical change that takes place when oxygen and hydrogen are combined to form H2O?
When oxygen and hydrogen combine to form water there is a chemical change, not a physical change.

You may, for example begin with water vapor and, if the temperature is low enough, it will condense (a physical change) to liquid water.
