The correct option is A True
Definition of matter
The matter is made up of very small particles called atoms. Atoms are the building blocks of matter.
According to the kinetic theory of matter, all matter exists in three states solid, liquid and gas
Solid state-
The particles are tightly packed.
The interparticle force of attraction is very strong.
The interparticle space is almost negligible and so the movement of particles is very limited and they move about their fixed position only.
the kinetic energy of the particles is very low.
Liquid state -
Particles are loosely packed.
The interparticle force of attraction is lesser than the solids and so the particles are present at some distance from each other.
The inter-particle space is more, and so the particle moves freely around other particles.
The kinetic energy of the particles is more than the solids.
Gaseous state -
In a gaseous state, the particle is present far apart from each other.
The inter-particle force of attraction is negligible as compared to solids and liquids. Hence the particle moves around freely and independently.
The interparticle space is very large and so the gases occupy the entire space available in a container and do not have a definite volume and can be compressed easily.
The kinetic energy of the particle is very high. The particles move around freely colliding with each other and also with the walls of the container.
Hence the given statement is true. ie,Inter-particle force of attraction is weakest in gases.
