Jawaban:

A. Most of the laboratory apparatus is made of glass because glass is a transparent material and we can see through it clearly. It does not react with most of the chemicals used in experiments. Glass withstands high temperatures.

B. It will withstand nearly all temperatures used in normal laboratory use. It is highly resistant to chemical attack. Its low coefficient of expansion allows it to be manufactured with relatively heavy walls giving it mechanical strength, while retaining reasonable heat resistance.
