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.
Is boiling water into steam is chemical change?
yes
Is heat changes h20 to steam a chemical change?
physical
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.
Is mixing popcorn steam a physical or chemical change?
it is a chemical change
Is water is heated and changed to steam a physical change or chemical change?
chemical
Is steam a chemical raection?
No. Steam is water vapor. Steam is formed by boiling water, which is a physical change.
When water changes to steam is it a chemical 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.
When water turns into steam is it a chemical change?
no, physical. The steam can return to water if cooled. Chemical changes are irreversible.

yes

Is water evaporating into steam a chemical or physical change?
It is a physical change because the change is reversible.
When a kettle is boiled why is it not a chemical change?
It is not a chemical change because the steam can be changed back when cooling and nothing new has formed. :)

Is production of steam a chemical or physical change?
The change from liquid water to steam is a physical change in the state of matter. Evaporation is the term for a liquid becoming a gas.
