GAS
Thestateofmatterwhichhasfluidity,highly
compressibleanddoesnothavedefiniteshape&volumeis
calledasaGas.
Example:Air,Clouds,Smokeetc

PROPERTIESOFGASES
1.Non Definite volume
2.Not definite shape
3.Fluidity
4.Minimum Density
5.More Diffusion
6.High Compressibility
7.Exert Pressure

PROPERTIESOFGAS
1.Not definite shape
2.Not definite volume(Occupy whole container)
(Intermolecular Space is more &
Force of Attraction is less)

PROPERTIESOFGAS
3. Non Rigid i.e. Maximum Fluidity
(Fluidity is the ability to flow)
(Its due to Intermolecular Space is more &
Force of Attraction is less)
Example:Gasinbaloonbefore&afterpressing

4. Minimum Density
DENSITY = Mass / Volume(gm/ml)
Example:1kgeachofIce,Water,Vaporhavedifferentdensities

5. It undergo DIFFUSION
(Spontaneous Intermixing Of Particles Of One Matter To
Another)
