What is Condensed Phases?
Condensed phases are the solid and liquid states of matter, as distinct from the gaseous state. In condensed phases, particles are in close contact and intermolecular forces are significant. The properties of condensed phases—density, surface tension, viscosity, and thermal expansion—are determined largely by the strength and nature of these intermolecular attractions.

Condensed phases are the solid and liquid states of matter, as distinct from the gaseous state. In condensed phases, particles are in close contact and intermolecular forces are significant. The properties of condensed phases—density, surface tension, viscosity, and thermal expansion—are determined largely by the strength and nature of these intermolecular attractions.
Understanding condensed phase behaviour is essential in materials science, chemical engineering (distillation, crystallisation), and physical chemistry (thermodynamics of phase transitions). Most industrial chemistry and biological processes occur in condensed phases.
Condensed phase reactions can release energy rapidly (runaway exotherms in concentrated solutions or melts). Thermal properties of condensed phases must be characterised before scale-up. Cryogenic condensed phases (liquid N₂, liquid O₂) present asphyxiation and explosion hazards.
