Question

How is molar polarisation of polar molecules affected with decrease in temperature?

Answer 1

For polar molecules, molar polarization increases with a decrease in temperature, while for non polar molecules, molar polarization is independent on temperature.

The total molar polarization$(P_M)$ increases with inverse in temperature$($ $1\over T$ $)$ for polar molecules.

When a graph is drawn for $(P_M)$ against $($ $1\over T$ $)$ , a finite, positive slope can be observed.
