A substance can take on three physical states: Solid, liquid, or gas. The main physical changes from a thermodynamic standpoint are the amount of entropy(disorder) of the molecules of the substance. Density, temperature, volume are also characteristically different at each physical state and can be used to manipulate compounds between the three.
a physical change is a change in any physical property of a substance, not in the substance itself

a physical change will only alter the appearance but will NOT change the substance to another substance =)
it would be physical change because physical change is when the substance stays the same

No. The whole idea of a physical change is one which does not alter the nature of the substance.
If form changes but identity doesn't change then it is a physical change.
No. The whole idea of a physical change is one which does not alter the nature of the substance.
A physical change occurs when the composition of a substance does not change. This means the substance retains its chemical identity but may undergo a change in its physical properties like shape, size, or state of matter. Examples include melting, freezing, boiling, or dissolving.
No.
A physical change does not change the substance.
