Chapter 12.3, Problem 25SSC

Interpretation Introduction

Interpretation:

Whether the solid which is formed by allowing a molten material to cool slowly to room temperature or one formed by quickly cooling the same material in an ice bath is more likely to be amorphous needs to be explained.

Concept introduction:

Amorphous solids are powder like which are not actual solids as these doesn’t have definite melting points.

Answer to Problem 25SSC

A molten material will be amorphous when it is cooled rapidly in an ice bath.

Explanation of Solution

A rapid cooling in ice bath leads to formation of amorphous solid. But if cooling process is slow then it leads to crystallization. The atoms are getting enough time to be arranged in a proper orientation o attain the structure of the crystal.

Conclusion

Fast cooling of a molten material in ice bath can give amorphous solid.
