Question

What is the transition temperature of $\alpha$ and $\beta$-sulphur?

• A. ${369}^{\circ }C$
• B. ${369}^{\circ }F$
• C. ${95.5}^{\circ }C$
• D. ${95.5}^{\circ }F$

Answer 1

The correct option is C ${95.5}^{\circ }C$

Transition temperature is where both dominant forms of sulphur, $\alpha$ and $\beta ,$ are stable. For sulphur, the transition temperature is $368.5K\left(or{95.5}^{\circ }C\right),$ below which $\alpha$-sulphur is most stable and above which, $\beta$-sulphur is most stable.
