Question :
Why the properties of solids , liquid and gases are different .?
Answer :
- In solids intermolecular forces are very strong and particles are closely packed . So they are incompressible .
- In liquids intermolecular forces are not very strong and particles are not much closely packed like in solids . So they can flow and do not have definite shape .
- In gases , the intermolecular forces are negligible so particles are allowed to move freely . So , they can occupy any space given to them .
