Consider a gravity-free hall in which a tray of mass $M$, carrying a cubical block of ice mass $m$ and edge $L$, is at rest in the middle. If the ice melts, by what distance does the center of mass of "the tray plus the ice" system descend?
As ice melts, COM would no shift, as there is no external force (not even gravity).
