Q. 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
A) Low thermal conductivity
B) High thermal conductivity
C) High specific heat
D) High melting point
Explanation
(a) When a piece of glass is heated, due to low thermal conductivity it does not conduct heat fast. Hence unequal expansion of it’s layers crack the glass
