No, when an ice cube melts, the atoms move closer together so it seems like a smaller amount. However, it does not lose mass, the number of atoms are still the same.
In a perfectly-insulated container, with a perfectly-insultated cover, all the energy of the hot water is distributed between the hot water and the ice cube. As the ice cube melts, this statement is still true, but the ice's latent heat of fusion may draw the hot water down to near freezing point, even if its mass is small compared to the mass of hot water.
True, a wet rock melts at a lower temperature!
That is a true statement.
True.
If it talks to u and says ''Hi I'm an ice cube put me in ur cup to make ur drink colder''
It is false that an ice cube melts when it's mechanical energy increases.

Yes, a true cube is symmetrical about several axes.
Yes, this is true
this is true and people a long time ago has already proved it. you might want to try it out yourself it is a fun experiment to see the ice fade into nothing!
Energy isn't "destroyed" and mass isn't "created" Basically mass is a "form" of energy. Much like ice is a "form" of water. So while one could, kinda, say "ice is destroyed when it melts into water" it isn't exactly true (even though it is no longer ice).
True...
if it is a true cube then yes, all 6 faces are congruent
not true
Very true.
That is a true statement.
