Why is an iceberg larger underwater than floating on water?

Because of the density.

Density of water: Density of ice = 10:9

Then according to the buoyancy: f = density of water * v row * g

And the gravity of the ice itself = the density of the ice * v ice * g

Buoyancy = gravity, you can calculate the volume ratio, you can calculate the volume ratio of the dismounted volume to the volume of the ice = 9:10, so the ice under the water accounts for 9 10, and there is only 1 10 above

In addition, if you want to know why the volume under the iceberg is larger than the above, you just need to know this simple fur, I feel that there are too many professional terms used below, which is not suitable for understanding, and you don't need to understand, you can know it with this simple junior buoyancy formula, so don't study its physical properties too much.

Finally, that netizen, please don't plagiarize my answers, and respect the fruits of other people's labor, okay?

A few upstairs were right, but overly complicated. To put it simply, although the density of ice is smaller than that of water, it is still relatively close, if the density is 1 3 of water, then it can be exposed by just half of it, and if it is greater than 1 3, it can only expose a small part.

The density of ice is approximately multiplied by 10 to the 3rd power = kilograms per cubic meter, which is precisely the reason for the density, so the ratio of volume above water to volume under water is always 1:9

Also: What are the physical properties of ice?

The properties that a substance can exhibit without chemical change are called physical properties, which include color, state, odor, melting point, boiling point, hardness, density, etc.

Ice: 1. It is a molecular crystal with intermolecular hydrogen bonding, which is slightly white, 2. It has low-temperature superconductivity, 3. Ice has low hardness and is easy to transform into a plastic state under long-term pressure.

4. The Mo-style hardness of pure ice at different temperatures is:

The compressive strength of 0 is 2 kg square centimeter.

The density of the ice is when the temperature decreases.

The degree density will also become smaller.

6. Ice has strong adsorption.

7. Most of the ice is a hexagonal lattice crystal.

The physical properties of ice can change with the change of crystal structure, and only the common properties in nature are listed above.

Because the density of ice is 1 ... Unit kg m3

Because the density of ice is the density of water, the density of ice is less than that of water, so it is able to float on the surface of the water.

Physical properties of water.

Very special, thermal expansion and cold contraction.

The principle that sometimes water does not follow.

Generally, objects are thermal expansion and contraction, but water does not follow this principle at 0---4, the density is the highest at 4, the colder the density, the lower the density, and the density is only when it freezes into a fixed one. So the same volume of ice rows.

The volume of the water is less, which means that the volume of water discharged by a piece of ice is smaller, so that more of the ice floats on the water.

The buoyancy received by the solid is equal to the weight of the discharged liquid, and if the density of the solid is greater than the liquid, it will sink, and if the density of the solid is less than that of the liquid, it will float. This is junior high school physics.

That's what you've learned!

Why does a solid block of ice float on the surface of the water? Because ice is less dense than water, water molecules.

It takes up more space in the solid state than in the liquid state, so the ice cube in the fixed volume is lighter than the same volume of water.

This is because ice is less dense than water, objects with a density lower than water will float in the water, objects with a density greater than water will sink in the water, and objects with a density equal to water will be suspended in the water and are in equilibrium.

The density of water under normal conditions is that, however, when the water condenses into ice, the volume increases, and the density decreases to the point that it is clear that the density of water is greater than that of ice, and in this state the ice will float on the surface of the water. When the density of an object is greater than the density of water, such as a block of iron.

The density is greater than the density of water, and the iron will sink when put in the water.

If we follow the law of thermal expansion and contraction of objects, water should be denser after cold contraction after freezing, and ice should sink. However, the physical properties of water are very special, when the unit mass of water condenses into ice, its volume expands, so the density of the scarlet becomes smaller, that is, the density of ice is smaller than that of water, so the ice will float on the surface of the water after the water freezes.

When the water freezes when it is cold, the ice cubes float on the water. Here's why.

Because the buoyancy in the water is relatively large, only a part of the iceberg will be exposed in this kind of situation, and the other parts of the larger sedan car are often in the water, so this is also the tip of the iceberg that people often say.

Mainly because of the density, the density of ice is smaller than that of water, so most of the ice sinks in the water.

This is because icebergs are relatively small, much less dense than water, and expand when they meet water.

90% of the volume of icebergs is submerged at the bottom of sea level.

Antarctic icebergs usually move around the Antarctic continent from west to east along the Antarctic Circumpolar Current (westerly drift), while Arctic icebergs follow the cold current that flows southward from the Arctic Ocean into the mid- and low-latitude Atlantic Ocean. The specific gravity of most icebergs is, so 6 7 of their mass is below the sea surface. The tip of the iceberg is only 1 10 of the entire iceberg.

There are about 40,000 icebergs in the Arctic Ocean that stay here all year round, coming from small ice sheets on islands on the edge of the Arctic Ocean, which are about 10 12 meters high and some 15 meters high, and 40 100 meters thick.

5 to 6 of the volume of icebergs are immersed at the bottom of the sea level.

It means that only 1 6 of the huge icebergs float on the water, and people can usually only see 1 6 of the huge icebergs exposed on the sea, which is a small part of the huge icebergs.

The volume sunk below the waterline Density of seawater = total weight of the iceberg.

Seawater density tons cubic meters》Iceberg density tons cubic meters, that is, about 90% of icebergs sink under seawater.

So icebergs float on top of the seawater.

It is approximately equal to 1 9 because ice has a density of g cm at 0 while water has a density of 1g cm. The density of ice and the ratio of water is 9 to 10. 9 10 underwater, 1 10 overwater.

How is it possible, the upper layer is ice water in the middle mixed with the water of the lower layer o degrees.

A total of 90 percent of them sink under the ocean.

Solution: Let the total volume of the iceberg be v, and according to the title, the iceberg floats in the water. So f float g rule.

p water * g * (v-v1) = p ice * g * v solution to obtain v = p water * v1 (p water p ice).

Hope it helps.

The specific gravity of the ice is.

So 1000 (cubic meters.

Solution: Because icebergs float in the water, so.

g float f float.

P ice * g * v ice p water * g * v row.

v ice (p ice p water )*v row (

Hope it helps.

The density of water is 1, and the density of ice is 9 times that of the underwater part, which is 10,000 cubic meters.

The specific gravity of the ice is.

So 1000 (cubic meters.

Hope it helps.

In winter, the rivers in the north are often covered with very thick ice, and even people and cars can pass on them. But in the water below the ice, fish and shrimp can still survive. Spring is coming, and the river is slowly flowing with the ice that has not yet completely melted.

These ice cubes are always floating on the water.

Why does ice always float on the water? This is because the volume of water grows by about one-tenth in the process of forming ice, so its specific gravity becomes smaller, and the same volume of ice is lighter than water, so the ice floats on the surface of the water.

Generally speaking, the property of general substances is thermal expansion and cold contraction, but water freezing is "cold expansion", and iced water is "heat contraction". In winter, we have to bandage the water pipes, that's the reason. If we don't wrap up the exposed water pipes, the water pipes will freeze and crack when the temperature drops below 0.

This is also due to the fact that the water freezes and grows in size, creating a huge force that bursts the water pipes.

If the same volume of water is compared with an object, the weight of the object is lighter than that of the water and it will float on the surface of the water, and the weight of the object heavier than the water will sink underwater. When a substance has both solid and liquid forms, in general, the same volume of solid is heavier than liquid, but the opposite is true for water.

According to Archimedes' principle, when ice is submerged in water, the ice floats in the water because it is less dense than water and has greater buoyancy than gravity.

Ice is less dense than water, and as a result, icebergs float on the surface of the water.
