PV/nRT for an ideal gas is called:
Correct answer: C. Compressibility factor
- A. Expansion factor
- B. Depression factor
- C. Compressibility factor
- D. Diffusion factor
Explanation
Compressibility Factor is also often defined as "the ratio of molar volume of gas to that of an ideal gas." It is expressed as Z = pV / RT. As it perfectly compliments the given statement, C option is the correct option.

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.
