why does an ordinary glass tumbler crack if very hot water is poured into it ?

Answers

Answered by Rivagada

Answer:

When boiling water is poured into a thick tumbler its inner surface expands. However, due to low thermal conductivity of glass, the expansion of outer surface of the tumbler is quite small. Due to uneven expansion of the outer and inner surfaces, the tumbler breaks.
