Physical because you are not changing the substance. For example water vapor(gas) can be condensed back into water. If you burn a piece of paper the ash cannot be changed back into paper therefore it is chemical. But because you are not changing the substance the answer is physical.

It is a physical change becasue the chemical makeup of the water molecule did not change - the molecule just changed state.
