[问答题]
The principal virtue ok n9 qmdcs05:hldg2app4 )y6 b5s1xd pfhz5rq7z0e g4 l Pyrex glass is that its coefficient of linear expansion is much smaller than t 07rqglz5h e4zhat 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.
