The molecules (or atoms or ions) of a liquid, like those of a solid (and unlike those of a gas), are quite close together; however, while molecules in a solid are held in fixed positions by intermolecular forces, molecules in a liquid have too much thermal energy to be bound by these forces and move about freely within the liquid, although they cannot escape the liquid easily. Although the molecules of a liquid have greater cohesion than those of a gas, it is not sufficient to prevent some of those at the free surface of the liquid from bounding off (seeevaporation ). On the other hand, the cohesive forces between the molecules at the surface of a mass of liquid and those within cause the free surface to act somewhat like a stretched elastic membrane; it tends to draw inward toward the center of the liquid mass, to draw the liquid into the shape of a sphere, thus exhibiting the phenomenon known as surface tension .

Answer 2

1. The intermolecular spaces are somewhat large and intermolecular forces fairly small as compared to the solids.

2. The molecular of the liquid have a large Kinetic energy.

3. It is on account of the larger Kinetic energy and large intermolecular spaces that the molecules can interchange their position.

4. It is on account of this reason that liquids take the shape of containing vessel and flow from higher to lower level.

5. The intermolecular forces in the liquids are sufficient to hold the molecules together and therefore, they have fixed volume.

6. They are incompressible.
