Why is the boiling of water a physical change?
A physical change is when a substance undergoes a process whereby its physical features change but its chemical features stay the same. A chemical change is when an object undergoes a process whereby its chemical composition changes. The water leaving as steam has undergone a physical change (evaporation) from a liquid state to a gaseous one, but no chemical change has occurred because it is still H2O. By definition, any change in the state of matter is a physical change. ...

Is boiling alcohol a physical change?
Boiling point is a physical characteristic because the matter changes state not composition. It is not a chemical change because nothing happens to the electrons in the outer shells of any of the atoms involved. Alcohol absorbs energy with he result that it changes phase, and such a change is by definition a physical change and not a chemical change. ...
Physical changes to substances produce different substances?
By definition a physical change is something that does not change a substance into a different substance (and by different I mean a different chemical structure). This does not mean that a physical change cannot cause a chemical change, which by definition is something that does change a substance into a different substance. For example, increasing the temperature of a substance is a physical change, but if you increase the temperature past a certain point, a substance like wood might combust with...
