Does the height of the mercury column decrease if the diameter of the tube increases in a barometer?
The height of the Mercury column is not affected by the diameter of the tube.
Here is the proof:
Pressure is force per unit area; P =F/A. Force, F = mass (m) x gravity acceleration (g), and mass = density( d) x volume (V)
Therefore, P = (d x V x g) / A. Since volume (V) = Area (A) x height (h), then
P = (d x A x h x g) / A, which upon cancelling A from numerator and denominator gives P = d x h x g. This shows that diameter of the tube has no effect on height of mercury inside the barometer tube.

When climbing a mountain with a barometer will the mercury level decrease or increase?
As you climb a mountain, the atmospheric pressure decreases with altitude, causing the mercury level in the barometer to decrease. This is because there is less air pressing down on the mercury in the barometer as you ascend, leading to a lower reading.
A decrease in the height of a column in a mercury barometer means that?
there is a decrease in atmospheric pressure. Atmospheric pressure is directly proportional to the height of the mercury column in a barometer. When the height decreases, it indicates that the pressure in the atmosphere is lower.
What does a decrease in the height of the mercury column usually indicate on a barometer?
low pressure system and stormy weather
When air pressure goes up the liquid in a mercury barometer goes?
When air pressure goes up, the liquid in a mercury barometer goes down. This is because as air pressure increases, it pushes the mercury in the tube to rise, indicating higher pressure.
Torricelli invented a device for measuring air pressure called a(n)?
Torricelli invented a device for measuring air pressure called a mercury barometer. It consists of a glass tube filled with mercury placed in a dish of mercury. The height of the mercury in the tube changes with variations in atmospheric pressure.
A decrease in the height of a column in a mercury barometer means that .'s surface?
When air pressure increases, the mercury in a barometer rises.
When air pressure increases the liquid in a mercury barometer would what?
The height of the Mercury column would decrease.
When climbing a mountain with a barometer will the mercury level decrease or increase?
As you climb a mountain, the atmospheric pressure decreases with altitude, causing the mercury level in the barometer to decrease. This is because there is less air pressing down on the mercury in the barometer as you ascend, leading to a lower reading.
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.
When air pressuer increases what does the mercury in the barometer do?
Air is "pushed" into the open end of a barometer when the pressure is higher, meaning the mercury closer to the closed end of the barometer - where the pressure is measured - will rise.

What does a decrease in the height of a column in a mercury barometer mean?
air pressure is decreasing
A decrease in the height of a column in a mercury barometer means that?
there is a decrease in atmospheric pressure. Atmospheric pressure is directly proportional to the height of the mercury column in a barometer. When the height decreases, it indicates that the pressure in the atmosphere is lower.

low pressure system and stormy weather
What is a barometer with Mercury called?
A mercury barometer.
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.
