Properties of liquids explanation from "summary" of Physical Chemistry by Robert G. Mortimer
The properties of liquids can be explained by considering the intermolecular forces that hold them together. The molecules in a liquid are constantly moving and interacting with each other. The strength of the intermolecular forces determines the properties of the liquid. One important property of liquids is surface tension, which is a measure of how difficult it is to increase the surface area of a liquid. Surface tension is due to the cohesive forces between molecules at the surface of the liquid. The stronger these forces, the higher the surface tension. Another property of liquids is viscosity, which is a measure of a liquid's resistance to flow. Viscosity is influenced by the size and shape of the molecules in the liquid, as well as the strength of the intermolecular forces. Liquids with larger molecules and stronger intermolecular forces tend to have higher viscosities. The...
