Is it always true that the molecules of a dense liquid are heavier than the molecules of a lighter liquid?

Liquid water is denser than ice due to

In the liquid state, water molecules are held together by

Molecular forces exist between the molecules of a liquid in a container. The molecules on the surface have unequal force leading to a tension on the surface. If this is not compensated by a force, the equilibrium of the liquid will be a difficult task. This leads to an excess pressure on the surface. The nature of the meniscus can inform us of the direction of the excess pressure. The angle of contact of the liquid decided by the forces between the molecules, air and container can make the angle of contact. The direction of the excess pressure in the meniscus of a liquid of angle of contact 2pi//3 is

In a meniscus of radius r , with excess pressure p in atmospheric pressure p_(0) , the force experienced is

The absolute entropy of a liquid is less than of the solid.

Write true or false for the following statements. When kinetic energy of the molecules of a liquid becomes more than the intermolecular forces then energetic molecules rapidly leave the liquid and change into the gaseous state.

Explain the nature of molecules in solids, liquids and gases.

How do water molecules form aggregates in the liquid state ?

Assertion: The Brownian movement is due to the bombardment on colloidal particle by the molecules of dispersion midium which are in the constant motion like molecules in a gas. Reason: Brownian movement provides a visible proof of the random kinetic motion of molecules in a liquid.
