Question

A container of volume 𝑉 has helium gas in it with 𝑁 number of He atoms. The mean free path of these atoms is 𝜆He. Another container has argon gas with the same number of Ar atoms in volume 2𝑉 with their mean free path being 𝜆Ar. Taking the radius of Ar atoms to be 1.5 times the radius of He atoms, the ratio 𝜆Ar⁄𝜆He is__________ (rounded off to two decimal places).

Answer 1

The correct answer is: 0.85 to 0.95 (approx)
