When you heat up water and it changes to steam is it a physical or chemical change?
It is a physical change. When water evaporates, it is still water. The molecules are only spread apart. A chemical change would be if a substance completely changes.

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 changes to steam it undergoes a chemical change true or false?
False. When water changes to steam, it undergoes a physical change, not a chemical change. Heating water to its boiling point causes it to change from a liquid to a gas, but the chemical composition of water (H2O) remains the same.
Is water is heated and changed to steam is it a physical or chemical change?
The changing of water to steam is a physical change because it is still water, but only in a different state. The steam can change back into water which is a reversible change. Chemicals changes cannot change back. They are permanent.
Is steam a chemical raection?
No. Steam is water vapor. Steam is formed by boiling water, which is a physical change.
Describe the physical and chemical changes that occur when a pot of water is boiled over a campfire?
The chemical changes are in the campfire- the wood combines with oxygen from the air, releases heat and carbon dioxide. The water does not have a chemical change, but does have a physical change- it changes from a liquid (water) to a gas (steam).
Is heat changes h20 to steam a chemical change?
physical
When water turns into steam is it a chemical change?
no, physical. The steam can return to water if cooled. Chemical changes are irreversible.
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 changes to steam it is chemical change?
it is a physical change because you can actually see the process
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 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.
When water changes to steam it undergoes a chemical change true or false?
False. When water changes to steam, it undergoes a physical change, not a chemical change. Heating water to its boiling point causes it to change from a liquid to a gas, but the chemical composition of water (H2O) remains the same.
