 [Well...The floating ice displaces its volume in water, therefore when the ice melts the volume should not change. however the density of ice is less than water, so it takes up more space that an equal volume of water, so when it melts the water that was previously the ice will take up less space so the water level may go down. i dont know...] 


Actually... if for example, 20g of water freezes into ice. then when it melts it will still have 20g of water in the container. so the water level will stay the same

 It's kind of a tricky question, because people know that ice is less dense than water, so you might want to say that when the ice melts, the water will take up less volume as a liquid than when it was frozen, but it is not that simple.

The ice cube is not completely submerged, so all of the ice cube's volume is not measured when measuring the level of the glass. In fact, the ice cube will displace as much water as is equal to the mass of the ice cube itself. Therefore when the ice cube melts, the water level will not change!

THIS ISN'T THAT COMPLICATED AS ITS BEING MADE

  • the ice is floating on the water in the container , so initially some water is displaced
  • secondly, when the ice fully melts,the level of water increases noticeably as compared to the level of water before immersing ice but increases negligebly as compared to the level of water when ice was immersed.

Water is a member of a very exclusive group of substances that are less dense as a solid than as a liquid. It is very important that ice floats and has numerous biological impacts; namely, all life on earth. Most substances will contract as they cool, their individual molecules slowing down and "staying put" until finally forming a solid. Water will also do this - up to a point. As the temperature of water drops, the molecules slow down and contract just like any other substance. But once it reaches 4� C, water will start to expand. The reason water does this lies in its hydrogen bonds. 

Hydrogen bonds 
Every molecule of H2O is bent - the two hydrogens hanging off the oxygen at angles (104.5� between hydrogen atoms in case you 're interested) to make a rough "L" shape. This bent shape causes the molecule to be overall polar. Oxygen has a higher electronegativity and "likes" electrons more, which results in the electrons spending more time with the oxygen. So the oxygen is slightly negative, and the electron-deprived hydrogens are slightly positive. Because the molecule is bent with one end slightly negative and one end slightly positive, the molecule is said to be polar. 

So now if we expand our view to, say, a glass of water, we will see water molecules running around and bumping into each other. Since every molecule in this glass has a slightly negative and a slightly positive end, there is going to be attraction between molecules. As one water molecule runs around, its negative oxygen is going to be pulled towards the hydrogen atoms of different molecules, and the hydrogens will be pulled towards the oxygen. Now what we have between the hydrogen and the oxygen is a hydrogen bond. Technically, a hydrogen bond is said to be formed when a hydrogen atom covalently bonded to one electronegative atom is also attracted to another electronegative atom (usually between a hydrogen and a oxygen or nitrogen in living cells). 

Hydrogen bonds separate molecules 
We know what a hydrogen bond is, so now we apply it to the freezing of water. When the molecules of water are still a liquid, they are free-moving and make/break hydrogen bonds very easily and frequently. The molecules can slip in and out at close proximity due to its high energy. But when the temperature drops, the molecules lose energy, slow down, and keep their hydrogen bonds for longer. Soon enough, at 4� C, the hydrogen bonds start altering the layout of the molecules. A single water molecule can only form a maximum of four hydrogen bonds with its neighboring molecules. At 4� C and below, a molecule will "keep" its bonds and lock into a crystalline lattice with its four neighbors. Then the molecules are at "arms length" so to speak and there are less molecules in a given space; the density is now lower. 

When the hydrogen bonds are able to form and be retained (as in ice), the density becomes 10% less dense than the water above 4 �C. And then, because a substance less dense than the liquid surrounding it will float in it, ice will float when placed in water.

The level of the water increases because the ice melts to form water which leds in the increase of water level

It is true because in both the cases weight of water displaced = weight of ice and weight of ice before and after melting is the same. 
This follows from Archimede's principle according to which a body floating in a liquid displaces weight of liquid equal to its own weight.
Water expands about 7% when it freezes, thats why it floats. But it displaces exaxctly its equivalent mass of water when it floats. When the ice melts there is no change in the amount of H2O in the vessel so the water level doesnt rise.
The level does not change because the ice is nearly at neutral bouyancy or barely floating to begin with, and it is colder. 

A tiny amount of the ice often protrudes above the water, so it does not have "exactly" neutral bouyency. But its close. One need only observe that icebergs have exposed surfaces, even in fresh water, that rise above the water surface, same thing happens in a glass. Since part is above water, the ice must be displacing a greater mass of water. So density change must play a part. 

As the ice melts it warms but does not expand, since warming ice above feezing causes contraction, not expansion (water reaches its maximum density at +4C, well above freezing). The warming ice cools the surrounding water thus decreasing its volume. The net result is that floating ice does not raise water levels when it melts, they stay the same. 

So if all the ice floating in the ocean were to melt there would be no change in sea levels

LEVEL OF WATER RISES BECAUSE ICE IS ADD IN WATER....
 
  • 0
remains same
 
  • -1
the level of water are not increasing beacause ice float on water and ice is a solid substance they are easily flow in water  beacuse fusion
  • 1
it rises because there was some water already in the container and ice melts and becomes water eventually increasing or rising the volume of the beaker

So, here the water level will remain the same when the ice cube will melt. Also, Stated by Archimedes that a floating object displaces an amount of water equal to its own weight. So as the water expands when it freezes, one ounce of frozen water has a larger volume than one ounce of liquid water.

In simple words 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.
