Why does the cup not overflow when ice melts?
When the cube melts, the surrounding liquid can move into the space it filled. If the glass contains only ice and water, it will not overflow because the amount of extra water will be equal to that previously displaced by the cube(s).
Does a cup get more full when ice melts?
The water level remains the same when the ice cube melts. A floating object displaces an amount of water equal to its own weight. Since water expands when it freezes, one ounce of frozen water has a larger volume than one ounce of liquid water.
Why do ice cubes stick together in a glass of water?
The interface between the ice and the liquid (the surface of the ice cube) is cooled by the ice cube, but heated by the liquid. The ice cube heats up in this process and the liquid cools down in this process (which is the main reason why you put the cubes in your drinks anyway).
What would happen to the water level in a glass if the ice cube floating in a glass of water will be completely melted?
It floats with a proportion of its surface below water level of such a volume as to displace its own weight of water (Archimedes Principal). When melted, the water produced by the ice will exactly fill the original volume that the frozen water displaced. Therefore no change in level.
Does water rise when ice melts?
This is because they are already in the water. The volume of water they displace as ice is about the same as the volume of water they add to the ocean when they melt. As a result, sea level does not rise when sea ice melts.
Why does water expand when it freezes?
When water freezes solid, at 32 degrees, it expands dramatically. Each water molecule is two hydrogen atoms bonded to one oxygen atom (H2O). The H2O molecule’s slightly charged ends attract the oppositely charged ends of other water molecules. In liquid water, these “hydrogen bonds” form, break, and re-form.
