Question

Out of thick glass tumbler, and thin glass tumbler, which will
crack more easily
pouring hot water into them?​

Answer 1

Answer:

Thick glass tumbler would crack more easily.

This happens because when thick glass placed in hot water, the surface warms first and expands. The deeper glass doesn't get warmed as quickly and doesn't expand as much. When one part of the glass expands more than another, it creates stress in the glass. When this stress exceeds the strength of the glass, it cracks, whereas this does not happen in thin glass tumbler.
