Question

What are the uses of glass/rubber tubes in the laboratory?

• A. It helps cold water to flow in and out of the condenser to allow heated water vapourise
• B. For liquid and gases in the experiment, rubber stoppers are used as plugs in the flask
• C. Rubber tubing is always connected to a condenser, helps in distillation
• D. All of these

Answer 1

The correct option is D All of these

Glass tubing is a long, clear tube used as a passage for liquid or gas in experiments.
Rubber stoppers are used as plugs in flasks or test tubes.
Rubber tubing is often connected to a condenser, which is a laboratory tool used in the process of distillation. The rubber tubing helps cool water to flow in and out of the condenser and helps the heated water vapor in the condenser return to its liquid state.
