A thermometer is used to measure temperature by the movement of a substance called mercury inside a sealed tube

A gastro esophageal tube is used when trying to treat Gastroesophageal reflux disease. Typically a tube isn't necessary and you can avoid the effects of GERD by just avoiding foods that cause the reflux to you.

Mercury is present inside the tube light.When we give supply to the tube light the mercury vapours excites and it produces uv radiation which then strikes the fluorescent material and produces light. Therefore it is called fluorescent light.
the light that is sent down the tube reflect of the sides making the light 'bend' down the tube and making it use internal reflection. once it gets to the end of the tube inside the patient, the image is reflected back to the person on the outside so they can see inside.
discharge tube can be used for indentifying electrons while tube light cxannot
You are seeing the spectrum of the metal used in a light bulb. In a florescent tube you are seeing ultraviolet light being transformed into visible light by the internal phosphor coating.
A boiling tube is used for boiling a liquid in
Imagine a plastic tube with an inside surface that is a high quality mirror. If you were to direct light into one end of this tube the light would bounce of the mirrored walls of this tube indefinitely, (regardless if the tube curves or twists) and you will see the light at the other end. if you were to send the light in an organised code it can then be used in communication. In scenes this is how fibber optics works. fibre optics are made with super fine quality glass drawn out to about the thickness of a human hair with plastic coatings around them to make the inside of the grass reflective and protect it.
The capillary tube is used on the inside of the refrigerators. It is a long copper tubing that is used as a thruster.
