Meaning and Definition
A tube, open at one end and filled with liquid, used to demonstrate the principles of atmospheric pressure and the creation of a vacuum.
Specifically, a device in which a column of liquid, typically mercury, is supported by atmospheric pressure in a sealed tube, creating a Torricellian vacuum above it; the foundational apparatus for a mercury barometer.

Common Mistakes When Using “torricellian tube”

- Confusing it with a general vacuum tube (electronic component) or a Bourdon tube (pressure gauge).
- Using it to refer to any vertical tube containing liquid.
FAQ
Frequently Asked Questions
Yes, specifically it is the original mercury barometer invented by Torricelli. The term 'Torricellian tube' emphasizes the experimental apparatus, while 'barometer' is the general measuring device.
Mercury's high density (about 13.6 times that of water) means atmospheric pressure supports a column only about 760 mm tall, making the apparatus manageable. A water column would need to be over 10 meters tall, which is impractical for a tabletop experiment.
It is the empty space (void of air) created at the sealed top of the inverted tube above the mercury column. It was one of the first artificially created vacuums.
No, it is primarily a historical term. Modern discussions use 'mercury barometer' or refer directly to 'Torricelli's experiment'. It remains valuable for teaching the history and fundamental principles of pressure.
A tube, open at one end and filled with liquid, used to demonstrate the principles of atmospheric pressure and the creation of a vacuum.
Torricellian tube is usually technical/scientific (physics, history of science) in register.
Torricellian tube: in British English it is pronounced /ˌtɒr.ɪˈtʃɛl.i.ən ˈtjuːb/, and in American English it is pronounced /ˌtɔːr.əˈtʃɛl.i.ən ˈtuːb/. Tap the audio buttons above to hear it.

Mnemonic
Think: TORRICELLI's Tube = The Original Really Remarkable Instrument Creating Empty Liquid-Less Interior. He used it to measure air pressure.
Conceptual Metaphor
THE ATMOSPHERE IS A FLUID COLUMN (The weight of the 'ocean of air' balances the column of liquid in the tube).
