Question

For real gases, $\frac{PV}{nRT}\ne ?$

• A. $1$
• B. $0$
• C. $0.5$
• D. $0.9$

Answer 1

Answer: (A)

$1$

For an ideal gas, $pV=nRT$. If $pV$ and $nRT$ are the same, and their ratio will, of course, be 1.

For real gases, $pV$ doesn't equal $nRT$, and so the value will be something different. $\frac{PV}{nRT}\ne 1$
