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.
Another way to look at it: You already know water expands when it freezes.
So if you freeze 1 litre of water, you’ll get more than one litre of ice. To get exactly 1 litre of ice, you have to take some of the ice away, so you have less stuff in that litre so it’s lighter.
