Many physical changes will not alter the identity. However, some physical changes, such as heating or cooling will result in phase changes and so the identity will be different. While ice and water are chemically the same, they are not identical forms of the substance.
This change in the state of matter (liquid to solid) is called freezing; it is a physical change, the chemical nature of the molecules is not changed.

When a substance melts, it changes state from solid to liquid. This does not alter the substance's chemical composition, so melting point is a physical property. Flammability means burning, and when a substance burns, it reacts with oxygen to produce a new substance that was not there before. This is therefore a chemical property.
