sometimes burst ?​

Answer 1

When you will check out the glass of water you kept in the freezer it would have turned to ice and the level of ice would be slightly higher than the level of water you marked..

This is because water expands on freezing. which means that water molecules would expand on freezing.

this is the reason why cold drinks kept in freezers sometimes burst.
