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 is the most compressible?
In general, Gases are the most compressible and solids are the least compressible. The main reason for this is the intermolecular forces which determine the physical state of a substance by altering the intermolecular spaces.
Which gas is least compressible?
| Liquid Compressibility, k | Ethyl alcohol 110 111 | Glycerine 21 21 | Mercury 3.7 3.8 | Water 45.8 46.4 |
|---|
How do you know which gas is more compressible?
Hint: To solve this you can use the formula of compressibility factor which is, [Z=dfrac{PV}{nRT }]. If the calculated compressibility factor is less than one then the gas is more compressible than ideal gas and if it is more than one, then the gas is less compressible than ideal gas.
Which of the following gas is easily compressible?
Therefore, gases are highly compressible because of the weak intermolecular forces of attraction between the gas molecules and a lot of empty space present between the gas molecules. Hence, option C is correct. Note- Compressibility is the property of being reduced to a smaller space by pressure.
Which state of matter has zero Diffusibility?
| List I List II | 1. Have no definite shape, volume or free surface A. Solids only | 2. Are highly compressible and less rigid B. Liquids only | 3. Have a definite volume, no definite shape and are slightly diffusible C. Gases only | 4. Are not compressible and have no diffusibility D. Liquids and gases only |

What has no definite shape?
solid: Has a definite shape and volume. ... gas : Has no definite shape or volume.
What is gas to solid?
Deposition is the phase transition in which gas transforms into solid without passing through the liquid phase. ... The reverse of deposition is sublimation and hence sometimes deposition is called desublimation.
What matter has the highest density?
Density is mass per unit volume. It can be measured experimentally or predicted based on properties of matter and how it behaves under certain conditions. As it turns out, either of two elements can be considered the element with the highest density: osmium or iridium .
Why is gas more compressible than liquid?
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. Gases are compressible because most of the volume of a gas is composed of the large amounts of empty space between the gas particles .
What is significance of Z 1 in a gas?
the value of Z tends toward 1 as the gas pressure approaches 0 , where all gases tend toward ideal behavior. the value of Z is less than 1 at intermediate pressures because the intermolecular forces of attraction cause the actual volumes to be less than the ideal values.
Which gas is called dry ice Why?
“Dry ice” is actually solid, frozen carbon dioxide , which happens to sublimate, or turn to gas, at a chilly -78.5 °C (-109.3°F). The fog you see is actually a mixture of cold carbon dioxide gas and cold, humid air, created as the dry ice “melts” ... oops, I mean sublimates.
When z1 gas is less compressible?
When Z>1, the gas becomes less compressible. The reason for this is that when Z>1, the forces of attraction between the molecules is weak . The attraction should be strong for compression to happen.
Is gas a highly incompressible fluid?
Explanation: 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 gases dont have?
Gases don't have a fixed shape or a fixed volume . The particles move around all the time and spread out. This is why a gas fills its container. A gas can be compressed into a very small space – this pushes the particles closer together.
What is the shape of gas?
A gas has neither a definite shape nor a definite volume . Like liquids, gases are fluids. The particles in a gas can move around one another freely. If a gas is released in a closed container, the gas particles will move in all directions and spread apart as they fill the container.
