- The water barometer is a weather ball barometer that was invented by Johann Wolfgang Von Goethe1. It consists of a sealed glass container with a long narrow open spout connected to it, partially filled with water12. Water is less dense than mercury, so air pressure will lift a certain volume of water much higher up a tube than the same volume of mercury3. The water will evaporate/boil at the top of the water column because there is a vacuum above it4. This water vapour will depress the level of water in the water barometer4.Learn more:✕This summary was generated using AI based on multiple online sources.

It was invented by Johann Wolfgang Von Goethe, which is why it is also called the "Goethe Barometer." This simple device consists of a sealed glass container with a long narrow open spout connected to it. It is partially filled with water.ownyourweather.com/how-a-barometer-works-and …The weather ball barometer consists of a glass container with a sealed body, half filled with water. A narrow spout connects to the body below the water level and rises above the water level. The narrow spout is open to the atmosphere.en.wikipedia.org/wiki/BarometerWater is less dense (less heavy, in effect) than mercury so air pressure will lift a certain volume of water much higher up a tube than the same volume of mercury. In other words, if you use water, you need a really tall tube and your barometer will be so enormous as to be impractical.www.explainthatstuff.com/barometers.htmlThe water will evaporate/boil at the top of the water column because there is a vacuum above it. This water vapour will depress the level of water in the water barometer. That is why mercury is used in a barometer: its vapour pressure is low and little evaporates into the vacuum. (The water barometer is also very cumbersome due to its height.)spark.iop.org/water-barometer
