Overview
Liquids are one of the three fundamental states of matter, exhibiting properties that lie between gases and solids. Unlike gases, liquids have a definite volume but no fixed shape, and unlike solids, their molecules can move past one another. These unique characteristics arise due to the balance bet
Key Concepts
These are attractive forces between molecules
These are attractive forces between molecules that determine the physical state and properties of substances. Types include dipole-dipole, dipole-indu
Vapour pressure is the pressure exerted
Vapour pressure is the pressure exerted by a vapour in equilibrium with its liquid in a closed system. It increases with temperature. Boiling occurs w
Molecules at the surface of
Molecules at the surface of a liquid experience a net inward pull due to unbalanced intermolecular forces, leading to surface tension. It causes liqui
Viscosity is the internal resistance
Viscosity is the internal resistance to flow of a liquid. It depends on the strength of intermolecular forces—stronger forces mean higher viscosity. T
Learning Objectives
- Explain the properties of liquids in terms of molecular structure and intermolecular forces
- Differentiate between evaporation and boiling
