Chemistry States of Matter (Gaseous & Liquid State)JEE Main

Inert gases such as helium behave like ideal gases over a wide range of temperature. However, they condense into the solid state at very low temperatures. This indicates that at very low temperature there is a:

(A)Weak attractive force between the atomsCorrect
(B)Weak repulsive force between the atoms
(C)Strong attractive force between the atoms
(D)Strong repulsive force between the atoms

Answer: (A)

Solution

Because such extremely low temperatures are needed before these gases condense, the underlying interatomic attractive (van der Waals) forces, while genuinely present,
