Question: 106
1. Which of the following sets of conditions would be LEAST likely to result in ideal gas behavior?
- A. High pressure and low temperature
- B. Low temperature and large volume
- C. High pressure and large volume
- D. Low pressure and high temperature
Correct Answer: A
Explanation:
Gases deviate from ideal behavior at higher pressures and lower volumes and temperatures, all of which force molecules closer together. The closer they are, the more they can participate in intermolecular forces, which violates the definition of an ideal gas. At extremely high pressures, low volumes, and low temperatures, the size of the gas particles becomes significant, which also violates the definition of an ideal gas.
