States of Matter 1 Question 52
52. Match the gases under specified conditions listed in Column I with their properties/laws in Column II.
| Column I | Column II | ||
|---|---|---|---|
| A.Hydrogen gas $(p=200 \mathrm{~atm}$, $T=273 \mathrm{~K})$ |
p. | compressibility factor $\neq 1$ |
|
| B. | Hydrogen gas $(p \sim 0, T=273 \mathrm{~K})$ | q. | attractive forces are dominant |
| C. | $\mathrm{CO}_{2}(p=1 \mathrm{~atm}, T=273 \mathrm{~K})$ | r. | $p V=n R T$ |
| D. | Real gas with very large molar volume |
s. | $p(V-n b)=n R T$ |

Solution:
- A. At $p=200 \mathrm{~atm}$, very high pressure, $Z>1$. Also, at such a high pressure, the pressure correction factor $\left(\frac{n^{2} a}{V^{2}}\right)$ can be ignored in comparison to $p$.
B. At $P \sim 0$, gas will behave like an ideal gas, $p V=n R T$. C. $\mathrm{CO}_{2}(p=1 \mathrm{~atm}, T=273 \mathrm{~K}), Z<1$.
D. At very large molar volume, real gas behaves like an ideal gas.
