Chapter 13, Problem 13Q

To determine

To explain: The reason that Pyrex glass has more heat resistance than the ordinary glass.

Answer to Problem 13Q

As the linear expansion coefficient, there will be more heat resistance as there is very little change in the dimensions of the Pyrex glass.

Explanation of Solution

Introduction:

The less the expansion coefficient, the more the materials have resistance to expand or contract.

As from the table data, the value of the linear expansion coefficient is very low as compared to ordinary glasses. The lower expansion coefficient means it has more resistance to expand when the temperature increases. As the Pyrex glass will expand less than ordinary glass so there will be a negligible change in the dimensions of the glass and having more heat resistance.

Conclusion:

As the linear expansion coefficient, there will be more heat resistance as there is very little change in the dimensions of the Pyrex glass.
