Arrange the strength of the forces of attraction between the particles of solids, liquids and gases from the strongest to weakest

• (strongest) gases > liquids > solids (weakest)

• (strongest) solids > liquids > gases (weakest)

• (strongest) gases > solids > liquids (weakest)

• (strongest) solids > gases > liquids (weakest)

Why does solid has a fixed shape?

• The particles are held by very strong forces of attraction. They can only vibrate about their fixed position. Hence, they have an orderly arrangement.

• The particles are held by weak forces of attraction. They can move rapidly in all directions. Hence, they have an disorderly arrangement.

• The particles are held by strong forces of attraction. They can slide over one another. Hence, they have an disorderly arrangement.

The diagram represent the arrangement of particles in ____________.

• gas

• liquid
