  2. A mercury barometer works by12345:
    1. Balancing the weight of mercury in a glass tube against atmospheric pressure.
    2. When atmospheric pressure increases, it pushes more mercury into the tube, raising the mercury column.
    3. Conversely, when the pressure decreases, the mercury level drops.
    4. The tube is filled with mercury at the base and placed upside down in a container called the 'reservoir'.
    5. The height of the mercury column can be used to gauge atmospheric pressure and forecast the weather.

    A mercury barometer is an instrument for gauging atmospheric pressure. The atmosphere exerts pressure on Earth’s surface, and that pressure can be measured when mercury moves up and down a tube. You can use the height of the mercury column to gauge the pressure in the atmosphere and hence forecast the weather.

    The working principle of a mercury barometer is based on balancing the weight of mercury in the glass tube against the atmospheric pressure. When atmospheric pressure increases, it pushes more mercury into the tube, raising the mercury column. Conversely, when the pressure decreases, the mercury level drops.

    The tube is filled with mercury at the base and placed upside down in a container called the 'reservoir'. It works by balancing the weight of mercury within the glass tube with the atmospheric pressure. When the weight of mercury is less than the atmospheric pressure, there is a significant rise in the mercury level in the glass tube.

    A traditional barometer, which is used for measuring air pressure, is a long, narrow tube that is open at one end and closed at the other end and typically filled with mercury. As the air pressure pushes on the mercury from the open end of the tube, the mercury level will rise. At sea level, the mercury will typically be pushed about 30 inches up.
