First, not all glass encounters boiling hot water will burst. But why some glass will break it?

  

ago, when buying glasses, the salesperson will tell you this is a cup of hot water or cold water cup. Cup of cold water in the face is boiling hot water will burst when that kind; and cups of hot water will not. But we should all now live in glass cup of hot water. Especially in China, we will always come with a glass of tea, so the glass does not touch the hot water is not a good thing. Water at a maximum temperature at one atmosphere pressure is 100 degrees Celsius, in our daily lives, we will not have more than 100 degrees of water.

  

If the thermal expansion and contraction is the only truth, then all the glass should be broken in the face of scalding hot water time. Facts not the case. Therefore, the heating or cooling is a part of the truth, in the manufacture of glass, there is no appropriate treatment, not the glass manufacturing right, is also very important reason. As long as the thermal expansion coefficient of glass to achieve relatively small, and the heat transfer coefficient for relatively large, so that the glass will not be broken. If we can look toughened glass, it will not burst.

  

In accordance with modern technology for the glass industry, in the face of hot water will break the glass is a manufacturing problem, not a physical phenomenon can not be changed.

  

These are the small series of water by the glass will crack you a brief introduction, if you want to learn more about it and other small glass of toxic knowledge also please pay attention to the small home security knowledge, hope the above content You help.
