How does a Barometer work?
Barometer is a glass tube that has one side open and the other side is closed. The open side of a barometer is placed in a mercury filled basin and the closed-end side is at the top. Instead of water, we normally use mercury for barometer. Because the density of mercury is more than water. The working process of a barometer is based on the balancing of mercury weight with respect to the atmospheric pressure. When the atmospheric pressure decreases, the mercury level also decreases and when the atmospheric pressure increases, the mercury level also increases. Rising the level of mercury of a barometer indicates improving weather and falling level of mercury indicates worsening weather. When the mercury level suddenly fall down, it indicates storming weather. The rising and falling level of mercury are calculated using a scale marked on the glass tube.

Barometer is an device in the study of meteorology. It is used to study atmosphere and weather phenomena. A Barometer is a scientific tool used to measure the atmospheric pressure at a specific temperature.
