Vedclass · Answer

(A) When a piece of glass is heated or cooled rapidly,the surface temperature changes much faster than the interior temperature due to its low thermal conductivity.This creates a temperature gradient within the material,leading to unequal expansion or contraction of its layers.Since glass is a brittle material,these internal stresses exceed its structural limit,causing the glass to crack.

$A$ piece of glass is heated to a high temperature and then allowed to cool. If it cracks,a probable reason for this is the following property of glass:
