Question

Given van der Waals constant for NH₃, H₂, O₂and CO₂ are respectively 4.17, 0.244, 1.36 and3.59, which one of the following gases is mosteasily liquefied?
(1) O₂
(2) H₂
(3) NH₃
(4) CO₂

Answer 1

Answer:

3) NH₃

Explanation:

Liquefaction of gases -

converting real gas into liquid state at high pressure and low temperature

-

Ease of liquifcation of gas depends on intermolecular interaction between gas molecule. NH3 has dipole - dipole interaction so it can easily liquify.

Answer 2

Answer:

(3) NH3

Explanation:

NH3 can be liquified easily ,it is a volatile liquid therefore it is used in for obtaining ocean thermal energy.
