A physical change involves the formation of no new substance and there is no change in the chemical composition of the substance undergoing the change.
It is a temporary change.
It is a reversible change as most of the time, the substance can be brought back to its original state.
Only physical properties like hardness, colour, etc. are changed during a physical change.
Energy is neither consumed nor released as chemical bonds are not involved in the physical change.
Examples: Conversion of Water from solid to liquid form, melting of the wax.
