CHXII01:THE SOLID STATE
318855
Statement A : On heating ferromagnetic or ferrimagnetic substances, they become paramagnetic. Statement B : The electrons change their spin on heating.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
All magnetically ordered solids (ferromagnetic, ferrimagnetic and antiferromagnetic solids) transform to the paramagnetic state at high temperature due to the randomisation of spins.

2 Chromium (IV) oxide
3 Benzene
4 Dihydrogen monoxide
Explanation:
Substances which show permanent magnetism even in the absence of the magnetic field are called ferromagnetic substances. e. g. Fe. Ni, Co, Gd and \(\mathrm{CrO}_{2}\).
