physical only, you are only changing its state, not its composition.
Is water is heated and changed to steam is it a physical or chemical change?
The changing of water to steam is a physical change because it is still water, but only in a different state. The steam can change back into water which is a reversible change. Chemicals changes cannot change back. They are permanent.

Is steam turning to water a chemical or physical change?
The formation of steam is a physical change. The chemical composition of steam (water vapor), is H2O, and the chemical composition of liquid water is H2O, so there is no chemical change going from liquid to gas (vapor/steam). Thus, it is a physical change.
When water changes to steam is it a chemical change?
