The temperature at which a real gas obeys ideal gas laws over an appreciable range of pressure is called ..........

What is Boyle's temperature? Give its relation with the value of $Z$.

$A$ plot of the compressibility factor $(z)$ vs $P$ is shown below for $H_2, He, N_2, CO_2$ and $SO_2$. Identify the plot for $CO_2$ gas.

$A$ certain quantity of real gas occupies a volume of $0.15 \ dm^3$ at $100 \ atm$ and $500 \ K$ when its compressibility factor is $1.07$. Its volume at $300 \ atm$ and $300 \ K$ (when its compressibility factor is $1.4$) is $........ \times 10^{-4} \ dm^3$ (Nearest integer).

If the compressibility factor $Z < 1$ at $STP$,what will be the molar volume?

The temperature at which the second virial coefficient of a real gas is zero is called:
