Obviously I know ice is just solid water but would ice be heavier than the same volume of water if you account for the expansion of water as it freezes?
I’m only curious because I know that as water freezes it traps air molecules inside its crystalline structure so I was wondering if it trapped enough to cause a distinguishable difference in weight between the two states.
Would depend, are you saying the same volume in same state or different states? If you freeze 1 volume of liquid water and compare it to a liquid same volume of water I would question it. Is the trapped air in ice from the ambient environment or is it dissolved air expelled from the water as the molecules lock together?
Would be interesting to freeze two samples in sealed containers with one being in a vacume.
