Well all off them really.. If you are eating ice it will melt in your mouth and change phase... When it gets to your stomach it undergoes a chemical change because of acids and enzymes. They could be could considered irreversible but since we are taking about atoms, you never know what will happen.

Ooh and only the chemical change is irreversible, a phase change can usually be reversed by changing the temperature or pressure
