Question

Differentiate between solids,liquids and gases on the basis of their kinetic energy of molecules, rigidity,fluidity ,intermolecular force and intermolecular space.

Answer 1

solids have high attractive force and it make all molecules hard ,but on liquids attractive force of molecules are low or kinetic energy are more then solid,but in air, molecules have no more attraction that why we pass our hand and body threw air easily.
