When water evaporates into a stream is it a physical change?
Physical change. The chemical formula of the steam still remains as H2O.
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.
Is steam turning into water chemical or physical?
Chemical changes are those in which the chemical composition of a substance changes during the process. But when steam turns into water or vice versa, only the physical state of the substance undergoes a change but the chemical composition remains same. Thus steam turning into water is a physical change.
When water changes is it a chemical change?
no. when water boils it is a physical change, because the actuall chemical structure is still H2O, it is just in the form of steam.
Why liquid water changing into steam is a physical not a chemical change?
The steam when cooled changes back to liquid water. A chemical change is usually not so reversible.

Physical change. The chemical formula of the steam still remains as H2O.
When water turns into steam is it a chemical change?
no, physical. The steam can return to water if cooled. Chemical changes are irreversible.

Is steam a chemical raection?
NO!!!! It is a physical change of water from liquid to gas(vapour).

When you heat up water and it changes to steam is it a physical or chemical change?
physical change because you are not doing anything to the object to change its ingredients or the way it is constructed and all you are really doing is adding heat.
Is water is heated and changed to steam a physical change or chemical change?
chemical
When water changes to steam is it a chemical change?
No, it is a physical change.
Steam is sometimes used to melt ice Is this change physical or chemical?
Physical. Steam, ice, and water are all H2O.
Of a kettle boils and water turns to steam is it a chemical or physical reaction?
Its a chemical reaction :]
Is a pan of water boils a chemical or physical change?
Physical, steam is still H2O.
When water changes is it a chemical change?
no. when water boils it is a physical change, because the actuall chemical structure is still H2O, it is just in the form of steam.
