LIQUIDS
The following characteristics are observed when the properties of liquids are examined;
1) The liquids cannot be practically compressed. Because moleculer
distance between them is reduced, they cannot come together any more.
2) Liquids retain their volume, even if their shape changes. In other words, no matter where they are placed, their volume does not change.
3) Fluids do not have their own specific shapes. They take their container’s shape.
Reason; liquid molecules can easily slip over each other.
4) Fluids are diffusive but they are slow, they can diffuse in each other, but the diffusion rate is very slow compared to gases.
5) A property can seen at surface formed by intermolecular gravitational force
is the surface tension. A molecule in the middle of the liquid; It is pulled in all directions by other molecules around it.
But the molecules on the surface of the liquid are only pulls into the liquid. Therefore, the surface area tends to be minimal. This behavior causes the liquid droplets to be spherical.
This is also the force that must be defeated to expand the surface. The surface tension of a liquid decreases as the temperature increases, because the increased molecular mobility with temperature affects the intercept of intermolecular attraction.
