If water if heated and changed into steam is this a chemical or physical change?
The change of water into steam is a physical change. This is because the molecules of water are simply being rearranged into a different state (liquid to gas) without undergoing any chemical reactions.
Is water is heated and changed to steam is it a physical or chemical change?

What is a physical change rather than a chemical change?
`A physical change is one in which matter is changed into another physical state without changing its chemical constitution(eg-ice melts to water,in both case substance is H2O).A chemical change is where there is a chemical change of the substance during the process(eg-CaCO3 is heated to form CO2 and CaO,here the new substance formed is unrelated chemically to parent substance.)
When water is heated and changed into o steam is that a chemical or physical change?

If an ice cube is placed in a pot that is heated what will happen after it has melted is it a chemical or physical change?
When ice melts and becomes a liquid it is a physical change. When the liquid boils and becomes gaseous it is a physical change. It is a chemical change when the molecular structure has been changed in some way, here it has not.
