Question

NUMERICAL PROBLEMS
1. Calculate the temperature of inversion of oxygen. Given that a = 1.31 litre? atmosphere per
mole? and b = 3-12 x 10-12 litre per mole. R = 8-4 J mole-'K-Atmosphere may be taken
approximately equal to 10% Nm-2 and litre 10-3 m?.
[Ans. 1007 K]
2. Given that vander Waals' constants for helium are a = 0.0341 litre atmosphere per mole?
and b=0-0237 litre per mole. Calculate the temperature of inversion. [Ans. 34.7 K 1
3. Calculate the change in temperature of helium at 100 K when throttled at a pressure difference
of 50 atmosphere. Given that for helium, a =0-034 litre atmosphere per moland b0-0237
litre mol! Given C, for helium is 20-75 J mol-'K-
(Ans. - 3.371 K)​
