Question

6. Why is a boiling tube made from
glass?
7. Why is a wire gauze placed under glass
apparatus, when heated?​

Answer 1

Answer:

6) It is thicker and longer than a standard test tube, which it resembles, so that liquid doesn't boil over. The entire tube can be immersed in a Bunsen burner flame because it is composed of borosilicate glass, a type of glass which is resistant to thermal shock and will not crack when exposed to extreme heat.

7) The wire gauze is usually used to keep glass beakers or flasks from breaking due to heat shock. This creates stress that can eventually cause the glass to break. When a Bunsen burner is used, a piece of wire gauze is often placed between the beaker/flask and a ring that is used to hold the beaker above the fire.
