Question

The temperature at which a real gas obeys the ideal gas laws over a wide range of pressure is:

• A. Critical temperature
• B. Boyle temperature
• C. Inversion temperature
• D. Reduced temperature

Answer 1

The correct option is B Boyle temperature

It is the Boyle temperature $T_B$ . At Boyle temperature, the first virial coefficient (B) vanishes and real gas approaches ideal behaviour.
$T_B=\frac{a}{Rb}$
Here, $a$ and $b$ are van der Waals’ constants.
