States of Matter 1 Question 41
41. The temperature at which a real gas obeys the ideal gas laws over a wide range of pressure is
(1981, 1M)
(a) critical temperature
(b) Boyle temperature
(c) inversion temperature
(d) reduced temperature
Show Answer
Solution:
- It is the Boyle temperature $T_{B}$. At Boyle temperature, the first virial coefficient $(B)$ vanishes and real gas approaches ideal behaviour.
$$ T_{B}=\frac{a}{R b} $$
Here, $a$ and $b$ are van der Waals’ constants.
