← ScienceWhich outcome arises when the gas constant deviates from its expected value during high-pressure gas compression?
A)Inaccurate pressure vessel volume prediction✓
B)Unanticipated turbine blade vibration amplitude
C)Catalytic deactivation through surface poisoning
D)Reduced nozzle exhaust velocity efficiency
💡 Explanation
When attractive intermolecular forces become significant at high pressure, the ideal gas assumption breaks down because gas compressibility factor Z deviates further from unity, making the observed pressure lower. Therefore inaccurate volume calculations results, rather than blade vibration, catalyst deactivation, or reduced nozzle velocity, which depend pressure changes and other mechanism.
