Consider a thick glass tumbler and a thin glass tumbler which are made of the same kind of glass. Some hot liquid is poured into them. Which of the following statements is correct?
the thick tumbler is less likely to crack because it is stronger
the thick tumbler is less likely to crack because it insulates the heat better, glass being a poor conductor of heat
Both tumblers are equally likely to crack because they are made of the same kind of glass
the thick tumbler is more likely to crack because uneven expansion persists for a longer time within the thicker glass
the thick tumbler is more likely to crack because it is heavier
Correct answer is D
Usually, when pour water into a glass, the more thick glass is easier to break. Because the glass tumbler is cold, when hot water is poured, and the inner wall expands rapidly due to thermal expansion and contraction.
