Compare the compressibility of solids, liquids and gases.
Compare the compressibility of solids, liquids and gases.
Step-1:
Solids:
All solids have a definite shape, distinct boundaries, and fixed volumes.
Examples of Solids:
Stones, wood, metals like iron, copper, nickel
Compressibility of solids:
- It is difficult to compress a solid even on applying pressure.
- This is because the constituent particles in the solids are so closely packed that they either do not come closer or do so when very high pressure is applied. So Solids cannot be compressed:
For example, we cannot press a piece of stone by applying pressure with our hands.
Step-2:
Liquids:
- In liquids, the particles are loosely packed.
- In liquid, the spaces between the particles are slightly more than that in a solid.
- Though, there is a quite strong force of attraction between the particles of a liquid which holds the particles together.
Examples of Liquids:
Water, kerosene, petrol, alcohol, benzene, milk
Compressibility of Liquids:
Liquids cannot be compressed much this is because their particles are still close together and possess very small spaces between them.
Step-3:
Gases :
Gases have neither a fixed shape nor a fixed volume. Hence, they do not have fixed boundaries.
Examples of Gases : Air, oxygen, carbon dioxide, steam
Compressibility of Gases :
- Gases are highly compressible.
- This is because the particles in the gas are far apart and there are large spaces between them. So, the gases can be compressed into very small volumes by applying large pressures.
Examples, the oxygen gas supplied to hospitals in cylinders, CNG (Compressed Natural Gas)
Step-4:
Comparison of the compressibility of solids, liquids, and gases:
- Unlike solids and liquids, gases are highly compressible
- This is because the particles in the gas are far apart and there are large spaces between them. So, the gases can be compressed into very small volumes by applying large pressures.
- Due to this property of gas, a large volume of gas can be put in a small metal cylinder by compression.
