no, physical. The steam can return to water if cooled. Chemical changes are irreversible.
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.
Nope - it's a physical change. The chemical composition is still H2O
physical change called vaporization where the liquid water changes to steam (water vapor) due to the heat energy supplied. This process involves a phase change from liquid to gas without altering the chemical composition of the water molecules.
Its a chemical reaction :]
No. Steam is water vapor. Steam is formed by boiling water, which is a physical change.
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.
chemical
No, it turns into steam. Water turns into ice at its freezing point.
evaporation.
The steam when cooled changes back to liquid water. A chemical change is usually not so reversible.
When you boil water on a stove until it turns to steam, it is a physical change. This shift occurs as water transitions from its liquid state to its gaseous state (steam) due to the application of heat. The chemical composition of the water remains the same throughout the process; only its state of matter changes.
