How Does a Barometer Work? The Answer Will Leave You Dazed
via typepad.com. High pressure is the opposite of low, which is caused by more air being above a particular area. This pushes the fluid or other measuring device of a barometer lower, since there’s greater than average air up above.... This happens because the mass of air in the bottle is fixed, so an increase in atmospheric pressure reduces its volume and vice versa. You can use any fluid, but water will evaporate into the bottle and air in the bottle will dissolve in the water.

Just like an atmospheric barometer, you can even use a water barometer to measure air pressure. In fact, a water barometer is the oldest form and the modern mercury barometers are …

  • A barometer is designed to measure changes in air pressure so you can more accurately predict the weather. Anglers and gardeners often use these instruments, along with hikers and other outdoor enthusiasts who want to know if there is a chance of rain in the next few hours.
  • A barometer is an instrument used to measure air pressure and track weather systems. The most common unit of measurement used in barometers is the millibar (mb).
  • A simple barometer tube (perhaps mercury, or water filled) can be used to measure atmospheric pressure A mercury tube needs to be relatively short -- a bit more than 30 in tall to do the job & a water tube needs to be more than 32 feet tall to do the same job (because of the large density difference between mercury & water). Any fluid can be used in a barometer tube as long as the fluid's
