The forces of attraction between the particles are maximum in _____ and minimum in _____.
solids, gases
The question compares the strength of interparticle forces of attraction across the three states of matter.
In solids the particles are packed very closely in a fixed arrangement, so the forces of attraction between them are the maximum.
This is why solids have a definite shape and volume and are almost incompressible.
In gases the particles are very far apart and move randomly at high speed, so the forces of attraction between them are the minimum.
This is why gases have neither a fixed shape nor a fixed volume and can be compressed easily.
Liquids lie in between, with intermediate forces of attraction, a definite volume but no fixed shape.
Therefore the forces of attraction are maximum in solids and minimum in gases, so the correct pairing is solids, gases.
