Question
Sulphur can also exist in an amorphous form – True or False?
Answer: Option A
:
A
When heated to 113∘COrthorhombic sulphur melts and if we continue heating this molten yellow liquid, it darkens above 160∘Cand becomes more viscous as the Sulphur rings break open and polymerize. The resulting helical Snpolymers can be extracted from the melt by pouring the molten Sulphur in water (called quenching). This super-cooled liquid is a metastable rubber-like material that slowly converts back to stable α−S8at room temperature. Different polymeric chains can have different number of atoms and isolating a particular strain becomes difficult. Obviously these polymeric forms are amorphous
