Condensed States

Quick Reference
Also Known AsCondensed matter, liquid and solid states, dense states

What is Condensed States?

Condensed states refer to the solid and liquid phases of matter in which atoms or molecules are closely packed together, in contrast to the vapour phase. The term is often used interchangeably with condensed phases. Reactions and properties in condensed states differ from those in the gas phase due to the importance of intermolecular interactions.

Properties & Characteristics

Condensed states (liquid and solid) are the two states of matter in which interparticle forces are strong enough to maintain particles in close contact. Solids have fixed positions (crystalline or amorphous), while liquids have close-packed but mobile particles. The transition between condensed states occurs at the melting point. Condensed states have characteristic densities, heat capacities, and thermal conductivities much greater than those of gases.

Uses & Applications

Condensed state chemistry encompasses all solid-state synthesis, solution chemistry, electrochemistry, and surface science. Most pharmaceuticals, materials, and biological molecules function in condensed states.

Safety Information

Thermal expansion of condensed phases in sealed containers can build up dangerous pressures on heating. Rapid transitions (e.g., superheated liquid suddenly nucleating into vapour — steam explosion) are hazardous industrial phenomena. Safe handling of molten materials requires high-temperature PPE.

Always consult the SDS/MSDS before handling any chemical. This information is for educational purposes only.
