For an ideal gas, the compressibility factor________________?
Correct answer: B. Is unity at all temperature
- A. Decreases with pressure rise
- B. Is unity at all temperature
- C. Is unity at Boyle's temperature
- D. Zero
Explanation
An ideal gas obeys PV = nRT exactly, so its compressibility factor Z = PV/(nRT) is unity at every temperature and pressure. Boyle temperature is a real-gas concept and is not needed for an ideal gas.
