What doesnot cause the height of mercury column to vary?
A change in the material of the container holding the mercury does not cause the height of the mercury column to vary. The height of the mercury column is determined by the atmospheric pressure acting on the surface of the mercury in the container.
How is a mercury barometer construct?
A mercury barometer consists of a tall glass tube filled with mercury inverted into a container of mercury. The mercury in the tube will fall until the weight of the mercury column is balanced by the atmospheric pressure pushing down on the surface of the mercury in the container. The measurement is then taken from the height of the mercury column in the tube.
How does a mercury pressure device work?
A mercury pressure device, such as a manometer, works based on the principle that the pressure of a fluid is directly proportional to the height of the fluid column. In a mercury manometer, a column of mercury is used to measure the pressure difference between two points. The difference in height of the mercury column indicates the pressure difference between the two points.
Why does the size of the cross-sectional area of a mercury barometer not affect the height of the enclose mercury column?
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.
What would happen to a mercury barometer when the air pressure is getting lower?
The height of the column of mercury would be lower.
Why the Mercury-in-glass thermometer first descends and then rise when put in flame?
When placed in a flame, the glass bulb expands rapidly. This increases the volume of the bulb and so the column descends. However, the glass then conducts the heat to the mercury so that it undergoes thermal expansion and the column rises.
Where is the obd connector in the 2000 mercury villager?
Under the dash slightly to the left of the steering column.
What is a huge rotating column of air that descends from a cloud?
A tornado.
What weather will accompany a decrease in the height of the mercury column in a mercury barometer?
the atmospere can not support the greater height column and the column of mercury will drop to the level in which the atmospere can support
How tall was the column of mercury in the barometer at sea level?
760 mm mercury column
What doesnot cause the height of mercury column to vary?
A change in the material of the container holding the mercury does not cause the height of the mercury column to vary. The height of the mercury column is determined by the atmospheric pressure acting on the surface of the mercury in the container.
What is mercury's row and column?
6th row (period 6) 12th column (group 12)
If we are experiencing high pressure what will happen to the column of mercury?
In a barometer, high pressure causes the mercury in the column to rise, indicating fair weather and stable atmospheric conditions. The higher the mercury column, the higher the pressure measurement.
What is a column of rotating wind that descends from a cumulus cloud to the ocean or a lake?
A waterspout is a column of rotating wind that descends from a cumulus cloud to the ocean or a lake. Waterspouts are similar to tornadoes but form over water. They can be dangerous for boats in the vicinity due to strong winds and rough seas.
Why does a column of mercury in a tube that is inverted in a dish of mercury have a height of about 760 at sea level?
The height of the mercury column in an inverted tube at sea level is approximately 760 mm due to atmospheric pressure. At sea level, the average atmospheric pressure is about 101,325 pascals, which supports the weight of the mercury column. The density of mercury and the gravitational force together create a balance, allowing the column to reach this height. If the atmospheric pressure changes, the height of the mercury column will also change accordingly.
As air pressure increases does the height of a column of mercury in a barometer increase?
Yes, as air pressure increases, the height of the column of mercury in a barometer also increases. This is because the higher air pressure pushes down on the mercury in the barometer, causing the column to rise. Conversely, lower air pressure will cause the column of mercury to fall.
