"We can easily move our hand in air, but not through any solid material." Justify the statement giving any three possible reasons.
The possible reasons to justify this statement are:
1. The forces of attraction between the particles are maximum in solids and minimum in gases.
2. The spaces between the constituent particles and kinetic energy of the particles are minimum in the case of solids and maximum in case of gases.
3. The solids have fixed shape and are not compressible. The arrangement of particles is most ordered in case of solids.
