Dear student,
In the case of thermometers, for example, Because there is vacuum in the top, and the capillary is too thin for free flow of mercury, mercury does not flow down when the mercury thermometer is held upside down or held vertically.
Hope this helps.
Please get back to us if you have further clarifications.
