According to kinetic theory of gases, at absolute zero of temperature
Water freezes
Liquid helium freezes
Molecular motion stops
Liquid hydrogen freezes
As we discussed in concept
Kinetic energy of a gas due to translation per mole -
- wherein
R = Universal gas constant
T = temperature of gas
At absolute zero kinetic energy = 0
molecular motion os gases stops.
Option 1)
Water freezes
This option is incorrect.
Option 2)
Liquid helium freezes
This option is incorrect.
Option 3)
Molecular motion stops
This option is correct.
Option 4)
Liquid hydrogen freezes
This option is incorrect.
