Detailed Solution

The breaking of a glass tumbler is a physical and irreversible change.
Irreversible changes are those changes which cannot be reversed. Physical changes are changes in which no new substance is formed. They may or may not be reversible. The breaking of glass is an irreversible change and a physical change as no new substance is formed. The glass is broken into small pieces and the pieces are still of glass only, so no new substance is formed. The broken pieces of the glass cannot be brought back to its original form, so it is an irreversible change.
