Say you have a container full of water, and a chunk of ice in there as well...when the ice melts, the water level/volume will be exactly the same as when the ice was initially placed into the container of water...is this true?
It is true for typical crystalline ice.
Ice is less dense than water so it displaces its weight in water and the extra volume of the ice sits above the water. As it melts the water level stays approximately the same. Of course if the ice chills the water it will become slightly denser so the water level could go down by a minuscule amount.
Amorphous ice does not have a crystaline structure and its molecules can be packed closely together. Ice formed by compressing snow under great pressure can be denser than water. This type of ice dropped into water would sink and as it melts the water level would rise.
the weight of the ice cube before it melted would have lowered the level of the water temporarily as the ice cube is solid and heavier. .once the ice cube melts, the water level appears to have increase as the ice cube is now not pushing the water down...
LOL I think I just confused myself
***ok so fill up a cup with water and ice all the way to the top...when the ice melts...you WILL SEE that the cup overflows...***
Not true, you'd be defying physics if that happened. Go to http://www.johnstonsarchive.net/environment/waterworld.html and read up
Why though? it doesn't make sense from a physics point of view. The floating ice would displace an amount of water equal to its own weight. Thus the water from the melting ice fits into the space occupied by the ice under the water level.
***as the ice cube is solid and heavier***
Ice is not heavier than water. Water expands when it freezes, thus becoming less dense...lighter than water by volume. If ice was heavier than water, than it would sink, would it not?
LOL indeed I am a science freak...gotta love me for that ;) haha
I'm just curious about this because someone told me about the melting ice thing, but they weren't able to back up their statement...so I was like wtf? hehe
LOL your the one asking the question and your debating with us...let me guess your a science freak who needs to believe in logic ...
hehehe your question was a tad hard, used up all my brain cells thinking about it
Naa..if the waters temp is between 0-4 degrees celcius then the volume of the water will be less than the volume of the ice because ice at 0 degrees is less dense than water in the interval 0-4 degrees celcius
omggg you better find the answer to this question as ill be glue to this page every time im online...hmmm think im turning geeky, science isnt my forte :-P
Ice floats, so part of the ice cube would be above water...when it melts, it would include the part of the ice that wasn't in the water, creating more water.
ice melts..(into its natural form) melts into a volume of water outside the glass & same happens in water...
so therefore... yes!!
ok so fill up a cup with water and ice all the way to the top...when the ice melts...you WILL SEE that the cup overflows...
no, there will be more water
