The height of the column in a Mercury barometer is determined by pressure, not force. Fluid pressures depend on density and depth-pressure at the bottom of a wide column of mercury is no different than the pressure at the bottom of a narrow column of mercury of the same depth. The weight of fluid per area of contact is the same for each. Likewise with the surrounding air. Therefore barometers made with wide barometer tubes show the same height as barometers with narrow tubes of mercury.

How do you make a homemade barometer?

Wrap a plastic sheet and seal it air tight to a jar and attach a small rod attach to the centre of the seal and allow it to pivot around the side if the jar could be a simple homemade barometer. Another model of barometer can be made using a sealed can attach to the tube inverted over a basin of water. Some trouble on these type of barometer is the pressurized and depressurised could be affected by the temperature but at the same temperature, the effect of movement will be solely on the atmospheric pressure. An inverted glass tube filled with mercury with vacuum space would be the best since the temperature would minimally affect but that would need large amount of mercury which is not readily accessible for a home experiment.


Are there unbalanced or balanced foces on Mercury?

There are unbalanced forces on Mercury due to its orbit around the Sun, leading to variations in its speed and direction. These forces cause Mercury to experience gravitational interactions that affect its trajectory.


How does length and bore affect sensitivity of mercury thermometer?

The sensitivity of a mercury thermometer is affected by its length and bore. A longer thermometer will respond more slowly to temperature changes due to the increased mercury column length, while a wider bore allows for more mercury movement and can increase sensitivity to small temperature changes.


Will a thermometer work up side down?

In general, a traditional mercury or digital thermometer needs to be held upright for accurate readings. Placing it upside down could affect the positioning of the mercury or the sensor, leading to inaccurate temperature measurements.


What are the disadvantages of using alcohol in a thermometer?

The disadvantages of using alcohol in a thermometer include its narrow temperature range compared to mercury, lower thermal expansion coefficient leading to less sensitive readings, and its tendency to evaporate more easily, which can affect accuracy over time. Additionally, alcohol is more flammable than mercury, posing a fire hazard.

Mercury barometer means you will have what kind of day?

A mercury barometer is an instrument which can be used to forecast the weather. The fact that there is a barometer does not affect the weather. You need to see what the barometer shows and interpret it.

Can humidity effect the reading of a barometer?

Yes, humidity can affect the reading of a barometer because changes in humidity can also impact air pressure. Moist air is less dense than dry air, which can cause slight variations in the barometer reading. It is important to account for humidity levels when interpreting barometer readings accurately.

How does mercury affect our water?

Mercury doesn't really affect our water, it affects and poisons us and other life in the water. It is a poison that interferes with the brain and nervous system.
