Solid, liquid, gas, and plasma are the four states of matter. Fluid cells have a consistent volume but not a consistent form. They cannot be stored without the use of a container. Its cellular attraction is central and mimics Brownian cell movement. The fluid moves from one level to the next at a consistent rate. The capacity and precise position of gas molecules is insufficient. A sealed container is required to house gas molecules. When compared to fluid and solid molecules, their molecular attraction is negligible. These molecules flow in all directions and move in a cellular, random, and consistent manner. The differences between liquid and gas are listed in the table below.
GAS
A state of matter in which matter freely diffuses in all directions is a gas. Regardless of the amount of gas present, matter takes up the entire space available. Gases have no definite volume and hence take up all the available space. The intermolecular interactions in gases are exceedingly minimal, allowing stuff to flow easily. The gases’ particles do not have a fixed shape or size. It is vital to remember that things in the gaseous state have no definite volume or structure. The gas takes up the entire volume of the container. Furthermore, gas is highly compressible and is thought to impose a finite amount of pressure on container walls.
‘Gases’ Physical Characteristics
- The kinetic energy of gases is very high.
- There are no intermolecular interactions between the gaseous particles.
- Gases adopt the container’s shape and volume.
- The pressure exerted by gaseous molecules is exerted in all directions.
LIQUID
A liquid is a condition of substance in which the volume is constant, but there is no discernible structure. The liquid conforms to the shape of the container it is placed in. The particles in a liquid have a more vital intermolecular force than the particles in a gas. Because of surface tension, the liquid always has a small surface area.
Because intermolecular interactions between molecules are modest enough to allow molecules to move relative to one another, liquids flow, and intermolecular forces exist between molecules close together.
At the molecular level, liquids exhibit both gaseous and solid qualities. Both liquid and gas are fluid, implying that the molecules can move due to intermolecular forces.
In both the gaseous and liquid phases, the substance has no set shape and instead takes on the shape of the container it is stored in.
Liquid Physical Characteristics
- Liquids have a constant volume but no constant shape.
- Under typical circumstances, liquids have higher boiling points than room temperature.
- Liquids are almost impervious to compression. Molecules in liquids are very near to one another.
Difference Between Liquids And Gases
- The Gas does not have a defined shape or size. However, the shape of the container on which it is placed is included. On the other hand, A Liquid has a specific volume but no particular shape.
- Gas has a lot of power. The Liquid’s strength, on the other hand, is modest.
- The Gas in the Gas has a partially structured yet structurally coordinated molecular arrangement.
That is the case with a liquid; the molecules assemble slowly.
- The attraction between gas molecules is minimal, but it is essential in liquid materials.
- The motion of gas molecules is calm, stationary, and random. On the other hand, the Brownian movement is used by liquid molecules.
- Gases must be kept in a well-sealed container. On the other hand, liquid necessitates the use of a container for final purposes.
- There is no such thing as a definite volume or shape for gas. On the other hand, the Liquid is an exact volume with no predetermined shape.
- It is simple to press the Gas button. Liquids, on the other hand, require energy to compress.
- Gases poured out in nearly every way. On the other hand, the fluid flows from a high to a low level.
- The intermolecular space in the gaseous state is vast, even more, significant in the liquid state.
- All three existing circuits have very low gas noise speeds. On the other hand, liquids are faster than gases but slower than solids.

Compressibility | Easy | Nearly difficult |
Fluidity | Flows in all the directions | Always flows from higher to lower level |
Intermolecular space | Large | More |
Speed of sound | Lowest among solids and liquids | Slower than solid but faster than gas |
During Phase Changes -: Changes Between Liquids and Gases
Evaporation-:
The process by which a substance changes from the liquid phase to the gaseous phase is known as evaporation.
Condensation -:
The process by which a substance changes from the gaseous phase to the liquid phase is known as condensation.
Conclusion:
The various gravitational forces between the molecules of the building material determine how they are classified. Because molecules in gases are less structured, the attraction is weak and can be quickly suppressed. However, in the case of a liquid, the cells are more structured. Because the gravitational attraction between molecules is greater than that of gas, it cannot be pressed as quickly. If enough heat is produced, anything on our planet may be changed to change its state. The idea is that not all substances must go through the solid-liquid-gas transformation. Some chemicals can go from solid to gaseous without going through a liquid stage.
