Click the correct answer.
have fixed shape and volume.
Liquids
Gases
Solids
Matter
The atoms/molecules are in continuous motion and hence possess
potential energy
kinetic energy
gravitational energy
manual energy
The state of matter is decided on the basis of
and interparticle spaces between the particles of matter.
interparticle forces of attraction
interparticle push
interparticle forces of repulsion
kinetic energy of particles
explains the behaviour of matter in different states.
Kinetic gravitational theory
Kinetic molecular theory
Kinetic manual theory
Kinetic muscular theory
The interparticle force of attraction is
in gases.
negligible
more than solids
more than liquids
more than liquids but less than solids
