Gas is a substance that exists in the gaseous state at a given temperature equal to more than the boiling point. E.g. Oxygen, helium, carbon dioxide, nitrogen, etc. a gas is a state of matter and it contains particles only in one state, that is gaseous state. they have very weak intermolecular forces among them. on the other hand, liquid has a definite volume and but not a definite shape. the molecules of the liquid are non-rigid. the main Difference Between Gas And Liquid is that gases have very large intermolecular spaces and can be highly compressed. whereas liquid has large intermolecular spaces and also can be compressed.
Difference Between Gas And Liquid in tabular Form
|gas molecules do have not a definite shape so they can adopt the shape of the container.||liquids also do not definite shape but they have their own definite volume.|
|gases have a random molecular arrangement along with more sparsely arranged.||liquids have random molecular arrangements but little sparsely arranged.|
|they possess the Highest energy due to the colliding of electrons.||they possess Medium energy due to the low colliding of electrons.|
|possess Free, random, and constant motion of molecules.||possess Brownian motion of molecules.|
|Needs a closed container to store||Needs a container to store|
|Minimum Molecular attraction||Medium Molecular attraction|
|No fixed shape or volume||No fixed shape but has volume|
|Easy to compress||Nearly difficult to compress|
|Flows in all the directions||Always flows from higher to lower level|
|Large space is present between the molecules.||more intermolecular spaces between the molecules.|
|Speed of sound is Lowest among solids and liquids||Speed of sound is Slower than solid but faster than gas|
What are Gases?
gases are considered one of the fundamental states of three matter states. they are made up of individual atoms or molecules of different elements. these elements are made from one type of atom or compound. the particles of gases are bonded with very weak forces of attraction that can move freely and filled all the space provided to them. Gas is a mixture for example air.
in fact, gases are spread everywhere in nature and the atmosphere of the earth like in solid earth rocks, seas, and rivers, oceans, sun, stars, clouds. they occurred in natural conditions. they possess several characteristics such as completely fill the vessels and adopt the shape of this container in which they are contained.
apart from liquid and solids, they are highly dependable on pressure and temperature. under normal conditions (0 – 100 ° C ) the coefficient of volumetric expansion of temperature is two orders higher than liquids is on average is 003 663 ° to 1°. however, the following characteristics can be shown in most of the gases:
- It is colorless and odorless.
- Lighter than air 1.8 times.
- Flammable and explosive.
- When leaking, it does not collect in lowlands but rises up.
What are Liquids?
liquids are physical bodies that possess the property of fluidity and also belong to the three fundamental states of matter. they belong to the intermediate position between gaseous state and solid state of matter. like gases, they do not allow to move freely and maintain their shape like solids. however, they can flow freely and can adopt the shape of a vessel in which they contain. the free movement of liquid molecules is responsible for the fluidity of liquids.
the condition in which they undergo defines its temperature and pressure. for example, water at standard temperature and pressure is a liquid, but can be converted into gas or steam by heating or can be converted into a solid substance by cooling. the molecules of liquids are also connected with each other with the help of intermolecular forces. but these forces are very weak as compared to solids but are stronger than gases molecules.
