The average density of pure ice is about 920 kg/m³. The average density of seawater is about 1025 kg/m³. By Archimedes's principle, the mass of the seawater displaced (i.e. the amount of the iceberg underwater) should equal the mass of the iceberg.
Using that principle, for each 1 m³ of seawater displaced it takes 1025 kg of ice - which will have a volume of 1025 kg x 1 m³/920 kg = 1.114 m³. In other words, 1m³ of the iceberg is submerged for every 1.114 m³ of iceberg.
1/1.114 = 0.89756
So, on average about 90% of the iceberg is submerged.
If the seawater is a little less salty, more of the iceberg is submerged.
If the iceberg is "dirty" - with stuff in it that is more dense than ice, more of the iceberg is submerged.
If the iceberg has voids (air pockets) it will be less dense and less of the iceberg is submerged.

∙ 15y agoYes,although water freezes at zero degrees. Clearly it carries on freezing waypast zero. The coldest temperature theoretically possible is 'absolute zero' which is about minus 273 degrees.. although its impossible to reach this temperature, trust me.. its very, very cold!

∙ 12y agoseven eighths or 7/8 of an iceberg is underwater.
Wiki User
∙ 14y agoRoughly 90% of ice is underwater. hence the quote "just the tip of the iceberg" because only 1/10th of the ice is visible above water.

∙ 14y agoIt should be 90 percent.

Does frost go deeper when the temp warms?
It might. It depends on what the average temperature is. If it is warmer but still below freezing, then frost can continue to go deeper. Warm temperatures do not CAUSE frost to go deeper though.
How do ice crystals form in a cloud?
When a liquid hits it's freezing point (0 Degrees Celsius) the liquid atoms start to crystallize and expand. Thus, creating ice! when the ice melts, the atoms separate again and decrease in size. Thus, liquid! There you go!
Freezing point in Everest?
The freezing point is the same no matter where you go. Does not matter if it is Everest or Death Valley-freezing is at 32 degrees.
What is the average temp of a tundra?
the average temp is............................................................................................................................................................................................................go find it your self u lazy bum
Do most raindrops start as snow or ice?
rain drops do not start out as snow or ice. they evaporate from bodies of water go up into the clouds and then fall back down to the ground. when it snows or hails the water first evaporates them becomes a cloud then as it falls back down to earth the freezing air will either turn it to ice or turn it to snow.

Does it go below freezing in Oklahoma?
Yes
Why does gritting and salting the roads help the snow and ice to melt?
Adding sand does not melt the ice, but it improves traction. Adding salt lowers the freezing/melting point, if the temperature is warmer than the new freezing/melting point of the salt/ice mixture then the ice melts. However there is a minimum temperature that this cannot go below, regardless of the salt used, and if the temperature is below this then salting the road does nothing and only sand will help.
Where in the world can you find snow?
Anywhere the temperature can go below freezing.
Would you rather go barefoot on freezing ice or on hot coals?
I would rather go barefoot on freezing ice. Ice may be uncomfortable and can cause frostbite, but it is less likely to cause serious and permanent damage compared to hot coals, which can cause severe burns.
Why doesn't ice cream go hard when frozen?
Ice cream does become quite hard when held at the proper freezing temperature.
What temp do you plug in your diesel truck?
I usually go for anything below 40
What is the temp for liquid to go through each state of matter?
Different fluids have different freezing and boiling points. Water has its freezing point at 0 degree Celsius while saline water has its freezing point at -67 degree Celsius.
How are fake ice skating rinks made?
under the ice is concrete. nothing can go in or out. the temp keeps the water frozen to create a thick layer of ice to skate on
What will happen to a Car left in the snow with water in radiator instead antifreeze?
If the temperature does not go below freezing then you're fine. Usually during a snowstorm, it doesn't go below freezing. However, if the water was still in your radiator and also in your engine without antifreeze and the outside temperature did drop below freezing, then you could potentially have a cracked block and/or a cracked radiator on your hands. Usually it's not too bad if the temperature doesn't go too far below freezing, but frozen water expands with a huge amount of force when it gets around 15-20 below zero.
When did the little ice age begin?
About 20,000 years a go when the earth entered a long period of freezing and cold
How do you get the driver's side door lock to work when the key will go in but won't turn on a 96 Lumina 3.1?
Is it below freezing when this happens? Maybe there's water in lock and it's freezing. Even if it's not below freezing, have you tried spraying some wd40 into the key hole? There's actually better stuff to squirt into the key hole...look for a product that contains graphite and try that. If below freezing, I've also seen people use a cigarette lighter to heat up there key and then insert the key, wait a few seconds for the heat to melt the ice and then try turning the key.
