There are three ice cubes floating in three different cups of water.
- In the first cup, the ice cube has a pocket of air inside.
- In the second cup, the ice cube has a pocket of liquid water inside.
- In the third cup, the ice cube has a metal pellet inside.
How does the level of water in each cup change as the ice cubes melt?
(a) no change, no change, no change
(b) up, no change, down
(c) down, no change, up
(d) no change, no change, down (e) down, no change, down
So, I know that if you have just normal ice, the level of water in each cup will be the same as the ice will displace the same volume of water when melted (since the ice has a lower density). I do not really know how to apply that knowledge when there are different materials within the ice.
My first instinct is that the ice will still be displacing how much it weighs, but the pocket of air will not add to the level of the water. And, I am not sure if the metal pellet or water will act in the same way as ice because they are both denser than ice. Any help?
EDIT: Also, I think it is looking at the water level after it melts. Sorry for the confusion.
