Why are gases easier to compress than solids or liquids?

Because most of the volume of a gas is empty space.........

We can use the Ideal Gas Equation to approximate gaseous density:

#PV=nRT#, so #P/(RT)=n/V#

But #n="mass"/"molar mass"#

And so #P/(RT)xx"molar mass"="mass"/V=rho#.

And thus for a given gas #rho# is proportional to #"pressure"#, and inversely proportional to #"absolute temperature"#.

On the other hand, in condensed phases, there is little dead space between atoms and molecules. And thus the volumes (and densities) of the condensed phases are essentially constant.

Deposition is the phase transition in which gas transforms into solid without passing through the liquid phase. Deposition is a thermodynamic process. The reverse of deposition is sublimation and hence sometimes deposition is called desublimation.

Why sponge though compressible is a solid?

Hint: The sponge is compressible being a solid because of the presence of air cavities inside the sponge. The sponge has numerous pores in it which can be referred to as air cavities in which air is trapped and on compressing the sponge it comes out.

Why are gases highly compressible in nature?

Gases are highly compressible to large vacant spaces between the molecules of a gas. As a result its intermolecular force of attraction is less and it has more distance between the molecules. Therefore it is simple to compress the gas.

Why are solids not compressible?

A solid’s particles fit closely together. The forces between the particles are so strong that the particles can not move freely they can only vibrate. This causes a solid to be a stable non-compressible shape with definite volume.

Which is less compressible solid or liquid?

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.

Which is more compressible air or water Why?

Compressibility of any substance is the measure of its change in volume under the action of external forces. … It indicates that air is about 20 000 times more compressible than water. Hence water can be treated as incompressible.

Which state of matter has the least compressibility?

Solid is least compressible because the solid is already densely packed so the solid is incompressible .

Why do gases have no definite shape because the particles of gases are?

Gases do not have a definite shape or volume because the molecules in gases are very loosely packed they have large intermolecular spaces and hence they move around. … The particles of solid are closely packed and occupy less space while particles of gases are loosely packed and occupy the complete space available.

What happens when a liquid is compressed?

A consequence of compressing a fluid is that the viscosity that is the resistance of the fluid to flow also increases as the density increases. This is because the atoms are forced closer together and thus cannot slip by each other as easily as they can when the fluid is at atmospheric pressure.

Why does the pressure of a gas increase when compressed?

The particles collide more frequently with the walls of the container. This means that the average force exerted by the gas particles on the container walls increases and therefore the gas exerts a greater pressure.

Why are gas particles so far apart?

Gas In a gas particles are in continual straight-line motion. The kinetic energy of the molecule is greater than the attractive force between them thus they are much farther apart and move freely of each other.

Which statement best explains the fact that gases can be compressed?

Which statement best explains the fact that gases can be compressed? The particles in a gas do not have a fixed volume. The particles in a gas are very far apart. The particles in a gas have no force of attraction (bonds) between them.

Is a solid hard to compress?

solids are very difficult to compress – the gaps between particles are already very small.

What process is solid to gas?

sublimation in physics conversion of a substance from the solid to the gaseous state without its becoming liquid. An example is the vaporization of frozen carbon dioxide (dry ice) at ordinary atmospheric pressure and temperature. The phenomenon is the result of vapour pressure and temperature relationships.
