How does increasing the temperature affect how closely a real gas behaves like an ideal gas?

• A. Temperature has no effect on how closely a gas behaves like an ideal gas.
• B. At higher temperatures, real gases behave more like ideal gases because intermolecular forces become less significant.
• C. At higher temperatures, real gases condense more easily and behave less like ideal gases.
• D. At higher temperatures, real gases deviate more from ideal behavior due to increased intermolecular attractions.

Answer: (B)

Verified step by step guidance

1. Recall that ideal gas behavior assumes no intermolecular forces and that gas particles occupy no volume.
2. Understand that real gases have intermolecular forces (attractive and repulsive) and finite molecular volume, causing deviations from ideal behavior.
3. Recognize that increasing temperature increases the kinetic energy of gas particles, making them move faster and reducing the relative effect of intermolecular attractions.
4. Because particles move faster at higher temperatures, they spend less time influenced by intermolecular forces, so the gas behaves more like an ideal gas.
5. Therefore, at higher temperatures, real gases tend to follow the ideal gas law more closely because the impact of intermolecular forces diminishes.
