Answer 2

The form sulphur exists at 100° C is allotropes of sulphur that is beta (β) sulphur

Explanation:

• β-Sulphur may be a yellow solid with a monoclinic crystal form and is a smaller amount dense than α-sulphur.

• Just like the α- form it contains puckered S8 rings and only differs from it within the way the rings are packed within the crystal.

• It’s unusual because it's only stable above 95.3 °C; below this temperature it converts to α-sulphur.

• β-Sulphur are often prepared by crystallising at 100 °C and cooling rapidly to hamper formation of α-sulphur.

• It’s a freezing point variously quoted as 119.6 °C[21] and 119.8 °C but because it decomposes to other forms at around this temperature the observed freezing point can vary.

• The 119 °C freezing point has been termed the "ideal melting point" and therefore the typical lower value (114.5 °C) when decomposition occurs, the "natural melting point"

Therefore,the form sulphur exists at 100° C is allotropes of sulphur that is beta (β) sulphur.
