The instrument, barometer, is used for measuring

Detalhes da Resposta
The instrument barometer is used for measuring air pressure. It works by measuring the weight of the air pressing down on the surface of a liquid (usually mercury or water) in a tube. The higher the pressure, the more the liquid is pushed up the tube. This can be used to determine changes in atmospheric pressure, which can indicate changes in the weather.
