उत्तर
Inter-particle attraction between atoms of gases is very weak. The five properties of gases which correlate as a consequence of the weak inter-particle attraction between particles of gases are:
- They have no definite volume.
- They have no definite shape.
- They have no free surface.
- They are less rigid.
- They rapidly diffuse with other gas particles.
