Which of the following conditions does NOT contribute to greater gas ideality?

• A. Negligible molecular volume
• B. Low pressure
• C. High temperature
• D. Strong intermolecular forces

Answer: (D)

Verified step by step guidance

1. Recall that an ideal gas is a hypothetical gas whose molecules occupy negligible space and have no intermolecular forces, allowing it to perfectly follow the Ideal Gas Law: \(PV = nRT\).
2. Understand that conditions promoting ideal gas behavior include negligible molecular volume, low pressure (which reduces molecular interactions), and high temperature (which increases kinetic energy, overcoming intermolecular attractions).
3. Recognize that strong intermolecular forces cause deviations from ideal gas behavior because they lead to attractions or repulsions between molecules, violating the assumptions of the ideal gas model.
4. Analyze each condition: negligible molecular volume, low pressure, and high temperature all help gases behave more ideally, while strong intermolecular forces do the opposite.
5. Conclude that the condition which does NOT contribute to greater gas ideality is the presence of strong intermolecular forces.
