Answer

A smaller coefficient of linear expansion means Pyrex glass won't expand as much as regular glass will.

Work Step by Step

Pyrex glass has a much smaller coefficient of linear expansion than ordinary glass. If it experiences differential heating (i.e., parts of it are heated more than other parts), the hotter parts won’t expand much. The smaller size mismatch between the regions makes Pyrex less likely to crack from internal stresses.
