Sorry i am not one of the big bosses but...........

As for 10.

The question says that it is a gravty free hall in which the system is kept
Ok so the ice melts but it being a gravity free space,there is no external force working upon it hence the centre of mass should not descend..

With my elementary knowledge of mechanics.......
Faults should be pardoned

All that is gold does not glitter
Not all who wander are lost
The old that is strong does not wither,
Deep roots are not reached by frost.
From ashes a fire shall be woken
From shadows a light shall spring
Renewed shall be blade that's broken
The crown less again shall be king.
