Question

What is the typical transformation observed between the allotropes of Tin (Sn) under specific temperature conditions?
Options
A White tin (non-metallic) transforms to grey tin (metallic) upon heating.
B Grey tin (metallic) transforms to white tin (non-metallic) upon cooling.
C White tin (metallic) transforms to grey tin (non-metallic) upon cooling.
Correct Answer
D Tin only exists as one allotropic form, irrespective of temperature.
Correct Answer

Option C is the correct answer.

Detailed Explanation

Page 13 illustrates this transformation: 'White tin Metallic' transforms to 'Grey tin non metallic' under 'cold' conditions, and 'Grey tin' transforms back to 'White tin' under 'heat'. Therefore, white tin (metallic) transforms to grey tin (non-metallic) upon cooling.

Hint

Refer to the diagram showing the interconversion of tin allotropes with 'cold' and 'heat' labels.
