fewer electrons than
$O_2$
two covalent bonds
V-shape
dipole moment
Hide Solution
Verified By Collegedunia
The Correct Option is
D
Solution and Explanation
Critical temperature is directly proportional to intermolecular force of attraction.
$H_2O $
is a polar molecule, has greater intermolecular force of attraction than
$O_2$
, hence higher critical temperature.

Liquid State
The liquid
state of matter
has the following properties:
As the particles moves it start moving everywhere inside the volume filled by the liquid.
Liquids have a strong inter-particle force, more inter-particle space than solids and enough kinetic energy.
It can be transformed into solids due to the solidification process.
Evaporation is the conversion of liquids to gases.
Liquid particles begin to flow more quickly when the temperature rises.
Liquids are difficult to compress because there is less space between particles for particles to migrate.
Constant volume but no constant shape.
In liquids, the rate of diffusion is faster than in solids.
Inter molecular attraction between particles is weaker than that between solids.
