Question

Some of the molecular solids upon heating produces small amount of
electricity, hence solid is (1) Piezoelectric (2) Pyroelectric (3)
Ferrielectric (4) Ferroelectric Ans given is Pyroelectric but
aren't Peizoelectric solids the ones that produce electricity?

Dear Student,

The correct answer is (2) PyroelectricPyroelectric are the crystals, which when heated produce a small electric current
Piezoelectric are crystals which when subjected to a mechanical stress, produces electricity
Since in the question electricity is produced on heating, so answer is (2)
