Why does a hot glass full of hot water break in the freezer?

Best Answers

Glass undergoes thermal expansion. Therefore, when it heats up, it expands and when it cools down, it contracts. Since glass has low thermal conductivity, the inside and outside of the glass does not reach an equilibrium temperature very quickly. read more

If you need it ready in a hurry, set the glass and its contents in a shallow pan full of warm, NOT hot, water and let it rest there until the water cools. Change out the water, continue this until the glass is no longer frozen. read more
