[问答题]
The principal virtue of Pyrex glass is that its coefficient of lin tr2nwb+zers *ytj /76ear exl9*ym/c ;cpri pansion is m m ci*9y;cprl/uch smaller than that for ordinary glass (Table 13–1). Explain why this gives rise to the increased heat resistance of Pyrex.

参考答案:
When Pyrex glass is heated or cooled, it will expand or contract much less than ordinary glass due to its small coefficient of linear expansion.  The smaller changes in dimensions result in lower internal stresses than would be present in ordinary glass.  Thus there is less of a chance of breaking the Pyrex by heating or cooling it.
