Why Does A Glass Bottle Explode When Poured With Boiling Water

In fact, it is because of thermal expansion that the heated part of the glass bottle will be heated and expanded while the cold part will remain unchanged. Moreover, the texture of the glass bottle is relatively brittle, so the heating of the glass bottle is uneven, which will cause the glass bottle to be unable to withstand the expansion of the heated part and crack, or explode
How can we prevent such situations from happening?
You should know that the test tube needs to be preheated before heating, right? In fact, it is to maintain a certain temperature at the bottom of the glass test tube, and then heat it towards the lower part, so that there is no danger. What if there is no preheating? That would be like a glass bottle, where the heated part expands while the other parts remain cold, and there is a risk of explosion.
Glass bottles
The principle of boiling a glass bottle in boiling water for 10 minutes is similar, which is to keep the entire glass bottle at a certain high temperature. At this time, pour hot water into the glass bottle. For a glass bottle, when the internal and external temperatures are similar, there will be no danger.
