a physical change is a change in any physical property of a substance, not in the substance itself
Melting ice to get water, or boiling water to get steam, doesn't change the identity of H2O.
Appearance is the property that can be altered. This is by physical change.

No, a physical property DOES NOT change the identity of a substance. That would be a chemical property which DOES change the identity.
Physical Change
is a physical change
It is a change of a physical property - for example the variation of temperature.
Changes of the matter that do not change the composition of the substance.
The physical property can be measured and quantified. It includes things like melting point, texture, color... A physical change is when a physical property is altered. The most common example is a change in physical state usually from a temperature change (solid melting to a liquid). A physical change does NOT alter the actual substance. (It's still water just in a different form.) MLZ Carpenter, Ph.D.
Boiling point is a physical property not a chemical property.
Change of state of a substance is a physical property!
