Explain the interconversion of 3 states of matter in terms of
force of attraction and kinetic energy of molecules

Dear student!
Interconversion of solid , liquid and gas is done by changing
the conditions like, solid has the strongest force of attraction in
the molecules so that they remain fixed and have minimum kinetic
energy, while the liquid have comparatively weak force of
attraction and higher kinetic energy of molecule while the gaseous
molecules have the highest kinetic energy and weakest force of
attraction so that they remain apart
So, to convert solid to liquid, solid is provided more energy so
that intermolecular force of attraction weakens and converts to
liquid while the liquid is converted to solid by cooling and
pressurizing so that the the kinetic energy decreases
Solid â‡” Liquid
For interconversion of liquid and gas , liquid is heated by
providing more energy so that K E of liquid becomes equal to gas
while the gas is cooled and condensed to convert it back to liquid
form
Liquid â‡” Gas
