The correctly matched pairs are:

$A$ pure crystalline substance,on being heated gradually,first forms a turbid-looking liquid and then the turbidity completely disappears. This behaviour is the characteristic of substances forming

An example of a network solid is

Crystalline metal can be transformed into metallic glass by

Which of the following arrangements shows the schematic alignment of magnetic moments of an antiferromagnetic substance?
