I have read the explanation because that this in numerous textbooks, but I to be struggling to recognize it via Archimedes" principle. If someone have the right to clarify with a chart or something for this reason I have the right to understand or a clean equation explanation that would be great.  Good question.

You are watching: Does ice take up more space than water

Assume we have one cube of ice in a glass that water. The ice displaces several of that water, raising the elevation of the water by one amount we will speak to \$h\$.

Archimedes" principle states that the load of water displaced will certainly equal the increase buoyancy force detailed by the water. In this case,

\$\$ extWeight the water displaced = m_ extwater displacedg = ho Vg = ho Ahg\$\$

where \$V\$ is volume that water displaced, \$ ho\$ is density of water, \$A\$ is the surface area of the glass and \$g\$ is acceleration due to gravity.

Therefore the increase buoyancy pressure acting on the ice cream is \$ ho Ahg\$.

Now the downward load of ice cream is \$m_ exticeg\$.

Now due to the fact that the ice cream is no sinking nor floating, these have to balance. That is:

\$\$ ho Ahg = m_ exticeg\$\$

Therefore,

\$\$h = fracm_ extice ho A\$\$

Now as soon as the ice cream melts, this height difference due to buoyancy goes come 0. Yet now an additional mass \$m_ extice\$ that water has actually been included to the cup in the type of water. Due to the fact that mass is conserved, the mass of ice cream that has actually melted has actually been turned right into an indistinguishable mass of water.

The volume of such water added to the cup is thus:

\$\$V = fracm_ extice ho\$\$

and therefore,

\$\$Ah = fracm_ extice ho\$\$

So,

\$\$h = fracm_ extice ho A\$\$

That is, the height the water has actually increased because of the melted ice cream is precisely the exact same as the elevation increase as result of buoyancy before the ice had actually melted.

Edit: for completion, due to the fact that it is elevated as a concern in the comments

Melting icebergs boost sea level rise, since the water lock contain is no salty.

Although many of the contributions to sea-level increase come indigenous water and also ice moving from land into the ocean, it turns out that the melt of floating ice causes a little amount the sea-level rise, too.

Fresh water, of which icebergs room made, is less thick than salty sea water. Therefore while the amount of sea water displaced by the iceberg is same to that is weight, the melted new water will certainly take increase a slightly bigger volume than the displaced salt water. This results in a little increase in the water level.

Globally, it doesn’t sound like much – simply 0.049 millimetres per year – but if all the sea ice at this time bobbing on the oceans were to melt, it might raise sea level through 4 to 6 centimeters.
