Increasing the compressibility of a gas (Z) decreases its.
Correct answer: B. Volume
- A. Pressure
- B. Volume
- C. Temperature
- D. Concentration
Explanation
The compressibility factor (Z) is a measure of how much a gas deviates from ideal gas behavior. A higher compressibility factor indicates that the gas is more compressible, meaning it can be compressed to a smaller volume than an ideal gas under the same conditions.Increasing the compressibility of a gas (Z) means that the gas can be compressed to a smaller volume, which decreases its volume (b).

About Real and Ideal Gases
An ideal gas is modelled as particles with negligible volume and no intermolecular attraction, obeying Boyle's, Charles's and Avogadro's laws through PV = nRT. Real gases deviate from this behaviour, especially at high pressure and low temperature, because particle volume and attractive forces matter; the van der Waals equation explains these corrections.
