It is around the metal glue tube.
To make the measuring apparatus a managable size i.e approx 10 inches high for Mercury tube. If water was used the tube would need to be much larger and the apparatus would be unmanageable when being carried around.
The Magnetron tube is quite different from the Klystron tube. The Magnetron tube is can only function as an oscillator only.
discharge tube can be used for indentifying electrons while tube light cxannot
The air molecules inside the test tube have a higher mobility when heated (they move around more). The collisions between these air molecules create more pressure on the inside of the test tube (force/area, where the force is the result of the increasing collisons and the area is the internal wall of the test tube.) This may result in the pressure inside of the test tube to be greater than the outside atmospheric pressure on the cork (actually atmospheric pressure on the cork and the frictional force on the cork created by the mouth of the test tube). If the internal pressure becomes greater than the external pressure (plus frictional force) the cork will come loose of the test tube.
The coiled tube of the inner ear is called the Cochlea.
The small intestine is a coiled tube in which chemical digestion occurs.
A long coiled tube in worms where many eggs are stored is known as the uterus. The ovaries are responsible for the production of eggs.

The coiled tube that lies behind the testes is called the epididymis. The epididymis is the part of the male's reproductive system that stores and transports the spermatozoa.
