Ice cubes in a drink
Some friends and I became involved in an argument at the bar tonight. Please help me settle it.
There are two glasses sitting on the table. Both glasses contain only liquor and ice, and at the time of the argument the top of the liquid is at the same level for each drink. One drink is 'fresh' and is full of ice all the way down to the bottom of the glass, while the other drink has been sitting for a few minutes so there is only a small amount of ice remaining. Neglect any ice floating slightly above the surface of the liquid. After a discussion about which drink contains more liquor, one party proposes a bet: if we were to wait several hours until all the ice in both drinks melted, the older one that is partially melted would have a higher liquid level. The others argued that the fresh drink that was full of ice would have a higher liquid level after all the ice melted. This bet could not have been carried out for obvious reasons, but if you have to back one of the two stances, which would you back? |

I believe Ice is less dense then water, as it floats. So the glass with ice would have more volume.

Longer evaporation time FTW.

Re: Ice cubes in a drink
Actually, now that I think about it, the drinks could not have been identically prepared if the almost-melted drink is at the same level as the fresh drink. That makes the question unanswerable without more information.

Re: Ice cubes in a drink
Ice that floats has no effect on level of water as it melts. Ice floats because it is less dense and displaces a volume of water of equal weight. As it melts this evens out.
OP states clearly that glass full of ice is full TO THE BOTTOM, therefore this ice is NOT FLOATING. As ice melts into water it becomes denser and therefore SHIRINKS in volume. So the level goes DOWN. |

Generally, when things get colder they shrink. The most notable exception to this is water; when it freezes it expands. Don't believe me? Test it out... place a can of coke in the freezer over night :P
When water turns into ice, the structure changes and it expands, so when the ice melts, the structure changes back it shrinks. |
