Why liquids are not compressible




















If the water compressed, it wouldn't "push back" out of the straw. Incompressibility is a common property of liquids, but water is especially incompressible. Water's lack of compressibility helps to push water out of water hoses handy for putting out fires , water pistols handy for bothering Dad , and in artistic water fountains handy for relaxing.

In these instances, some pressure is applied to a container full of water and rather than compress, it comes shooting out of an opening, such as the end of the hose or the end of a small pipe, as in this fountain. If water was highly compressible, it would be harder to create enough pressure for water to shoot out of the nearest opening.

Kids make good use of water's uncompressibility when they play a game of water-balloon tossing. When you squeeze the balloon too much, the balloon's skin will fail before the water inside compresses—it will burst in your face long before the water will compress even an infinitesimal amount.

When I was 7 years old, water's incompressibility got me in big trouble. I was analyzing the compressibility of water by soaking a sponge with water, smushing it up, and watching how much water came back out. To test if water compressed, I added some red food color to the water, soaked it up, and sat on my parent's new white carpeting to prove my theorem. I thought that since water was trapped in the sponge, I could squeeze the sponge and the water would compress.

My theorem was painfully disproved, as the water squirted out rather than compress. Well, I was a kid, how was I to know that the compressibility of water at room temperature is only about 0. But, squeeze hard enough and water will compress—shrink in size and become more dense Envision the water a mile deep in the ocean. At that depth, the weight of the water above, pushing downwards, is about times normal atmospheric pressure Source: University of Illinois at Urbana-Champaign Ask the Van.

A liquid is a sample of matter that conforms to the shape of a container in which it is held, and which acquires a defined surface in the presence of gravity. When a liquid is cooled, the atoms or molecules lose kinetic energy. If the temperature becomes low enough, the liquid becomes a solid. Water is a good example.

A solid is a sample of matter that retains its shape and density when not confined. Examples of solids are common table salt, table sugar, water ice, frozen carbon dioxide dry ice , glass, rock, most metals, and wood. When a solid is heated, the atoms or molecules gain kinetic energy.

Skip to content Home Why are liquids less compressible than gases? Ben Davis May 31, Why are liquids less compressible than gases? Why is a gas easier to compress than a liquid or a solid quizlet? Why are gases highly compressible while solids are almost incompressible?

Why are solids incompressible? Why are gases incompressible? Which gas is incompressible? Can gas be compressed yes or no? Gases are highly compressible because their molecules are far apart. There are many empty spaces between the molecules. We can also ask ourselves, why is the solid incompressible? Dry matter is incompressible because the molecules are very narrow and the intermolecular space is small or insignificant.

Liquids have more space than solids but less than gases and are therefore less compressible. However, solids have insignificant space and are therefore incompressible. Are solids and liquids also compressible? The dry matter is incompressible and has constant volume and shape. Liquids are incompressible and have a constant volume but can change shape. A liquid form is determined by the shape of the container it is in. Can the liquid be compressed?

The answer is yes, you can compress water or almost any material. However, it takes a lot of pressure to achieve compression. For this reason, liquids and solids are sometimes referred to as incompressible. What is the compressibility of the liquid? As a result of compression, the molecules are confined to a smaller space. Hence, the density increases. The viscosity, which is the ability of a liquid to resist its motion, also increases.

The reason is that when molecules are brought closer, the spacing between them becomes so small that the attractive forces start to dominate. The molecules cannot slip on top of each other as freely as they would at atmospheric pressure normal conditions.
