The principal virtue of Pyrvc i,hxwjt7yb- sbz09 ym3.)kn0v.rxex glass is that its coefficient e(ux21 (88cnz34a g v76y0dys es ec+dpmzuya of linear expansion is much smaller than that for ordimu (y ccx4ev3gys1e8a8unayd2+ zsep(067d znary 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.
