Question

Which of the two Ar and Kr, have greater
boiling point and why?​

Answer 1

Answer:

The van der Waals force increases with the increase in the size of the atom, and therefore, in general, the boiling and melting points increase from He to Rn. Helium boils at −269 ∘C. Argon has larger mass than helium and have larger dispersion forces.
