A
The inside expands more rapidly than the outside
B
The inside expands less rapidly than the outside
C
The expansion is even
D
It does not expand
Ask EduPadi AI for a detailed answer
Correct Option: A
When boiling water is poured into a thick glass tumbler, the inner surface of the glass comes into contact with the hot water and heats up rapidly, causing it to expand. However, the outer surface of the glass remains relatively cooler and expands less. This uneven expansion creates stress within the glass, leading to cracking.
