Well, an aneroid barometer, is called an aneroid barometer- but, a barometer measures air pressure, and an aneroid barometer is a barometer that contains no liquid.
Aneroid
The rubber piece inside some coil springs is called a coil spring isolator. It is used to reduce noise and vibrations by providing cushioning between the coils of the spring. It also helps to prevent metal-to-metal contact, which can reduce wear and tear on the spring.
The kind of barometer you are referring to is a aneroid barometer. It uses a metal chamber (an aneroid cell) which expands or contracts with changes in air pressure. This movement is then converted into a reading of air pressure on a dial.

Lucien Vidie, French scientist, invented the aneroid barometer in 1843.
spring = the season after winter spring = a coiled spiral as in a spring inside a mattress
No, an aneroid barometer does not use alcohol. It measures atmospheric pressure using a small, flexible metal box called an aneroid cell, which expands or contracts with changes in pressure. This movement is then converted into a reading on the barometer.
Aneroid barometer is an airtight metal chamber that is sensitive to changes in air pressure
as mercury does not sticks to the glassbeing a metal , it is shinny and hence, it is clearly visible
A barometer measures air pressure using a metal chamber from which some air has been removed. The most common type is the mercury barometer, where the air pressure pushes down on a pool of mercury in a glass tube to indicate atmospheric pressure.
