Answer the following :

A thick glass tumbler often cracks when boiling water is poured into it. Why?

When heat is applied to any object it expands. This is the reason why a thick glass tumbler cracks when boiling water is poured into it. As the heat is transferred from boiling water to tumbler it will cause the glass to expand, glass being solid will resist to expansion and will cause cracks in the glass tumbler.
