Glass suddenly expands
Glass suddenly contracts
Water evaporates
Glass reacts chemically with water
Answer is Right!
Answer is Wrong!
The correct answer is A. Glass suddenly expands.
When hot water is sprinkled on a hotter glass tumbler, the outer surface of the glass comes into contact with the hot water and expands. The inner surface of the glass, however, is still in contact with the cooler air and does not expand as much. This difference in expansion causes the glass to break.
Option B is incorrect because glass does not suddenly contract when it comes into contact with hot water. In fact, glass expands when it is heated.
Option C is incorrect because water does not evaporate quickly enough to cause the glass to break.
Option D is incorrect because glass does not react chemically with water.
