a physical change

because the water is still water just the appearance of it has changed. It is also known as a phase change because the boiling is just a phase once it is off the heat it will be normal water and if you freeze it it will become ice, but once you leave it out again its just water. Nothing has been added to it so therefore how can it be a chemical change.

If you really think about it you cant get the water back after it was absorbed because you can not collect gas or gather it up to be water once again.By:jariver dunlap.

It is a physical change because no new substance is being formed. It is still H20 and the steam when condensed can be reversed back to water. :)

It is a physical change. The molecules themselves do not undergo any change. They just gain more energy.

Even though some of the H2O is changed from liquid to vapor, it is still H2O.
