Question

to what Rotating polar molecules is proportional to
​

Answer 1

Explanation:

Dipole-dipole interaction energy between stationary polar molecules is proportional to 1/ r^3 and that between rotating polar molecules is proportional to 1/ r^6 where 'r' is the distance between polar molecules.

Answer 2

Dipole - dipole interaction energy between stationary polar molecules is proportional to 1/r^3 and that between rotating polar molecules is proportional to 1/r^6 where ‘r’ is the distance between polar molecules
