Cause Effect
Attraction forces bet. particles Bonding of particles (Shape)
Strong Solids have definite shape (not flow)
Relatively weak Indefinite shape (flow)
Weak Indefinite shape (flow)
Interparticle space Volume & Compressibility
Small Definite volume & incompressible
Relatively large Definite volume & incompressible
Very large Indefinite volume & compressible
Motion of particles Diffusion
Vibrated in fixed position Very slow
More freely Medium (average speed)
Randomly & completely freely Very fast
in all directions
The compression of gases reduces the interparticle spaces & this leads to
decreasing the total volume of gas without changing the volume of particles.
(Volume of gas decreases by pressure)
