Question

Expansion coefficient of pyrex glass is much more than that of ordinary glass.

• A. True
• B. False

Answer 1

The correct option is B False

1. When a solid is heated it expands in all directions.
2. Glass is found in the ordinary form in nature.
3. But there are different types of artificial glass also in which one type is pyrex glass.
4. Pyrex glass is used to make glassware that is resistant to heat, chemicals and electricity.
5. The linear expansion coefficient of pyrex glass is low compared to ordinary glass.
6. It expands less for the same rise in temperature.
7. This makes the pyrex glass useful to make glassware.

Thus, the given statement is false.
