NO!!!!
It is a physical change of water from liquid to gas(vapour).
No. Steam is water vapor. Steam is formed by boiling water, which is a physical change.

No, it is a physical change.
yes
Vapor steam cleaners use fresh water to create steam which loosens dirt and allows you to clean without using harmful chemical and pollutants. This is especially important if you have children or pets.
Physical. Steam, ice, and water are all H2O.
Because the transformation of iron in oxides is a chemical raection, an oxydation. A new compound (molecule) is formed.
no, physical. The steam can return to water if cooled. Chemical changes are irreversible.

it is a chemical change
how does the controlled varriables affect the rate of reaction
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.
Steam from a kettle is a physical change.
chemical
The steam when cooled changes back to liquid water. A chemical change is usually not so reversible.
Its a chemical reaction :]
