It changes properties.
Physical Changes:
Physical changes are changes in the appearance but not in the chemical properties. Some physical changes can be undone so the item can be put back to almost its past form.
Chemical Changes:
Chemical changes are the changes in chemical properties. Chemical changes also change in appearance and/or leave behind traces to prove that a chemical change occurred. Chemical changes create a new substance when they happen, e.g., cooking an egg. Chemical changes cannot be undone as the molecules, patterns and properties have been changed.
How to tell them apart:
The way to tell the difference between chemical and physical changes is by the changes that it went through. There may be clues that a chemical change appeared because of sound, light, gas production or an odour. A physical change does not involve any of these.
