Chemical that changes polarity when heated?

[BTruesdell07]

Is there a chemical that when heated its polarity changes?

Polarity? I don't know what you mean - electronic dipole moment? Steroisomerism?

Dipole moment is not affected by temperate.

Perhaps he/she is referring to the orientation of the individual molecule itself with respect to its symmetry properties, in that sense you may want to consider heating a rubber band, although I don't know if this would be the best example.
