S-I: Helium shows only positive deviation from ideal behavior at room temperature.
S-II: Helium is an inert gas.
S-II: Helium is an inert gas.
View answer and explanation
Correct option: B
Both statements are correct and statement-II is not correct explanation of statement-I
The correct answer is B because both statements are correct, but the inertness of helium doesn't explain its positive deviation from ideal behavior, which is due to its small size and weak intermolecular forces.

A quantity of hydrogen gas occupies a volume of at a certain temperature and pressure. What volume would half this mass of hydrogen occupy at triple the absolute temperature and the pressure were one-ninth that of the original gas?
In deriving the kinetic equation we make use of the root mean square speed of the molecules which is:
Consider the following statements for kinetic molecular theory of gases
