Intermolecular attractive forces cause certain real gases to exhibit compressibility factors below one.
Is it true that intermolecular attractive forces cause certain real gases to exhibit compressibility factors below one?
Compressibility factors below one in real gases are a direct consequence of intermolecular attractive forces dominating over repulsive volume effects under specific temperature and pressure conditions, a foundational concept in thermodynamics that requires no citation.
Verdict: COMMON KNOWLEDGE · 0 sources for, 0 against · Last checked
The claim describes a fundamental, textbook thermodynamic property of real gases where attractive forces (represented by the 'a' term in van der Waals-type equations) pull molecules together, making the molar volume smaller than that of an ideal gas and causing the compressibility factor Z to drop below 1. While papers discuss real gas behavior and equations of state, this relationship is a foundational physical principle taught universally in introductory chemistry and physics, qualifying it as common knowledge.
