When water evaporates into steam, it undergoes a physical change rather than a chemical change. This process involves the transition of water from a liquid state to a gaseous state due to the addition of heat, but the chemical composition of H₂O remains unchanged. Therefore, the molecules retain their identity, only changing their state of matter.
Physical change. The chemical formula of the steam still remains as H2O.
No, water evaporating into steam is a physical change rather than a physical property. A physical property is a characteristic of a substance that can be observed without changing the substance's chemical composition, whereas a physical change is a change in the substance's state or appearance without altering its chemical structure.
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.
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.
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.
No. Steam is water vapor. Steam is formed by boiling water, which is a physical change.

no, then it is gasEDIT: The chemical formula for pure water is always H2O - regardless of whether it's in the form of ice, water or steam ! Snakester1962 (Supervisor)
no, physical. The steam can return to water if cooled. Chemical changes are irreversible.

chemical
The change of water to steam is a physical change, not a chemical change. In this case, the water molecules are simply changing phase from a liquid to a gas, but the chemical composition of water remains the same.

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.
Its a chemical reaction :]
Physical, steam is still H2O.
