When you heat up water and it changes to steam is it a physical or chemical change?

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.

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?
No, it is a physical change.
How is physical change and chemical change different?
A physical change is when some thing's shape or volume is changed. But a chemical change is a reaction between two or more objects to create something new and you can't get back what you originally started with.
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.
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).
When water changes to steam it undergoes a chemical change true or false?
No. It is still water. So that makes it a physical change.
When water changes to steam is it a chemical change?
No, it is a physical change.
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.
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 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.

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.
