After all, why does ice swim? Science answers!

When you put ice in a glass of water or another drink, you may have noticed that the liquid swims on the surface of the liquid like a refrigerator in Antarctica. However, if I bought a small stone in the same size and weight as an ice cube, I would realize that it would sink instead of swimming. Later, Why does ice swim instead of sinking?

So, regardless of the size of the ice, Be a cube to cool your drink or gigantic iceberg in the middle of the cold ocean, and both will continue to swim on the surface of the water until it completely melts.

Scientists explain that this phenomenon may appear intuitive, because when the rocks are often placed in the water, they are directly associated with intensity. What determines that an object sinks or swims in water is the relationship between intensity, that is, mass and volume.

For example, if you place a low -density object on the surface of a lake like a part of a lake, it will float because the water is relatively dense from styrofoam. Already a large iron rod sinks immediately when placed in a river, because the density is much larger than water.

But is the difference big? After all, ice is nothing but solid water. Many people believe that they become heavier than liquid water by consolidating it.

However, this is not exactly correct in the case of ice. Floating because the density is lower than water itself. Science explains that ice is about 9% less dense than liquid water..

Since it is more dense, the water pushes the ice to the surface and allows it to swim. For this reason, in frozen rivers and lakes, the liquid water remains below, while ice occurs on the surface and allows fish and other water animals to survive even at extreme cold temperatures.

“Therefore, water is one of the few substances that are really less intense in solid form and fall from 1,000 to 917 pounds per cubic meter. So he floats instead of sinking, so that he develops as a layer on the surface of the lakes and rivers instead of sinking under the surface in winter and accumulating from the background. Brit Britannik encyclopedia explains.

Why does ice swim?

Most of the substances are in solid state, it is more intense, But ice is an exception because its density is lower than liquid water.. This is mainly due to the molecular structure of the ice.

Water (H2O) has molecules formed by two hydrogen atoms and an oxygen. The positive load of hydrogen atoms is affected by the negative load of oxygen atoms from other molecules and forms connections that scientists call hydrogen bonds.

In solid state, these connections regulate the water molecules in an open crystalline structure, where the molecules are further away from the liquid state. This organization reduces ice density compared to liquid water; We cause fluctuation.

Even the largest ice blocks, such as the icebergs, float in thicknesses ranging from 30 to 50 meters in the ocean. Even freezing of water plays an important role in various parts of the planet. In the Antarctica Ocean, sea ice affects ocean currents and reflects the solar radiation that helps regulate the temperature of the planet.

Thus, if all frozen water in the polar and continental glaciers has a sign, the level of the oceans will significantly increase. As a result, floods will take place in various coastal areas and will change the world’s climate balance.

Currently, global warming worries scientists, because the oceans are warming up and can melt floating ice platforms in Western Antarctica.

This is directly related to ice fluctuations, because these platforms function as natural obstacles that hold the ice of the world. With its decreases, terrestrial glaciers can shift faster to the ocean and significantly increase the sea level.

Archimedes Principle

Fluctuating of ice, also, An object dipped in a liquid is exposed to a push force equal to the weight of the displaced liquid.

Since the ice has less density than liquid water, it moves enough water to balance its weight, a phenomenon that allows swimming. Thus, a piece is dipped and the other is exposed to the surface.

When he discovered this possibility, Greek mathematician and philosopher Archimedes de Syracuse realized that fluctuation was directly related to intensity: As in the case of ice, an object floats in water. If it is more intense like a stone, it sinks.

“The principle of Archimedes, the law of physical fluctuation, was discovered by Greek mathematicians and inventors. He states that any body (gas or liquid), which is completely or partially dipped into a rest fluid, is exposed to the effect of rising or pushing force, which is equal to the weight of the liquid that is displaced by the body.

Antarctica is the coldest continent on the planet today, but it was not always the case. In the past, the landscape was surrounded by forests and a very different climate. Do you want to know more? Understand when Antarctica was not the last ice. Until next time!
