If boiling water is poured into a thick drinking glass as well as a very thin wine glass. Which of the two is more likely to crack?
"Think about how the temperature change affects the material, and which one is more prone to sudden stress..."
The thick glass is more likely to crack since glass is a poor conductor of heat. In a thin glass, the heat passes more quickly from the glass into the surrounding air, causing the glass to expand equally. When hot water is poured into a thick glass, the inner surface expands, but the outer surface does not. It is this extreme stress on the glass that causes it to crack.
