MCQ
According to kinetic theory of gases, at absolute zero of temperature:
  • A
    Water freezes
  • Molecular motion stops
  • C
    Liquid hydrogen freezes
  • D
    Liquid helium freezes

Answer

Correct option: B.
Molecular motion stops
This model is described for an ideal gas and assumes that the particles does not interact in any other way.
It is known that the root mean square velocity of a particle is proportional to the absolute temperature Also for zero absolute temperature, the velocity is also zero.
