What does it mean for matter to be compressible?
Compressibility is the measure of how much a given volume of matter decreases when placed under pressure. If we put pressure on a solid or a liquid, there is essentially no change in volume. The kinetic-molecular theory explains why gases are more compressible than either liquids or solids.
What are highly compressible?
Gases are highly compressible. This is because of the weak intermolecular forces of attraction between the gas molecules. Also, there is a lot of empty space present between the gas molecules which make them highly compressible.
Why are gases highly compressible?
Answer: Gases are compressible because the intermolecular space is very large in gases, whereas liquids are not compressible because in liquids, the intermolecular space is less.
What is the compressibility of plasma?
Liquids are non-compressible and have constant volume but can change shape. Matter in the plasma state has variable volume and shape. Plasma contains ions and electrons, both of which can move around freely.
What does compressible mean in chemistry?
(Chemical Engineering: General) If something is compressible, its volume can change when pressure is applied to it. For fluids of variable density, such as compressible gases, special rules apply. A fluid is compressible when its density changes with pressure.
What is compressibility in chemistry class 9?
Compressibility is the measure of how much a given volume of matter decreases when placed under pressure. If we put pressure on a solid or a liquid, there is essentially no change in volume.
Which is compressible in nature?
High compressibility of gases is very useful to us. Compressed natural gas is used as fuel in vehicles. 4. A sponge has holes filled with air and this makes it easy to compress it.
Which of the following is a compressible?
Notes: Gases show high compressible because the molecules of gases are very very loosely packed and there is too much space between them so by compressing it is comes close and close and close and as its intermolecular space is more than solid and liquid it can be more compressed compared to the both.
What is the most compressible gas?
Solid helium is by far the most compressible element, to be followed by solid neon; on the other hand Kr, Xe and Em are substantially less compressible than the alkali metal directly following them.
Which gas is least compressible?
Detailed Solution. Due to the strong intermolecular forces of attraction, the molecules in solids are tightly packed which is why they are the least compressible.
Is plasma compressible or incompressible?
It’s similar to neutral fluids where, for instance, in situations when the flow speed is well below the sound speed it is valid to treat the fluid as incompressible. However, very few things in space plasmas actually qualify as incompressible.
Is liquid compressible or incompressible?
Liquids are always considered to be incompressible fluids, as density changes caused by pressure and temperature are small. While intuitively gases may always seem to be incompressible fluids if the gas is permitted to move, a gas can be treated as being incompressible if its change in density is small.
What is a compressible fluid?
A compressible fluid is a fluid in which significant density variations that occur during its flow have to be considered, as is usually the case with vapors and gases.
What does lumen mean in medical terms?
Medical Definition of lumen. 1 : the cavity of a tubular organ or part the lumen of a blood vessel. 2 : the bore of a tube (as of a hollow needle or catheter) 3 : a unit of luminous flux equal to the light emitted in a steradian by a uniform point source of one candle intensity.

What is the role of mechanical compression in the normal venous system?
In the normal venous system, with distal mechanical compression flow augmentation is seen, which becomes particularly useful to prove patency in the smaller calf vessels. Open in a separate window
What is the lumen of a vertebral artery?
A lumen in anatomy can also refer to an aperture or an opening within a fixed structure, such as the circular hole in a vertebral bone through which the spinal cord courses. An aneurysm can increase in size until it blocks off the entire lumen of the vessel, or it ruptures.
