If air pressure is getting lower, you would expect to see the mercury in Torricelli's barometer rise. This is because low air pressure allows the mercury in the barometer tube to be pushed up by the weight of the atmosphere.
The pressure will be reduced (depending on circumstances)
If you hold a mercury thermometer from its bulb, the heat from your hand can cause the mercury to expand and rise in the tube, giving an inaccurate reading. Additionally, mercury is toxic, so it is not safe to handle a broken thermometer. Always handle thermometers by the plastic casing to avoid these issues.
When the area decreases, the force required to maintain the same pressure will increase according to the formula pressure = force/area. This relationship is known as Pascal's principle.
If you let the air out of a balloon, it will deflate and decrease in size as the pressure inside the balloon equalizes with the external pressure.

The height of the Mercury column would decrease.
The height of the Mercury column would decrease.
The height of the Mercury column would decrease.
if a meteorologist says that the air pressure is getting lower what you expect to see happen to Torricelli's mercury barometer
The height of the Mercury column would decrease.
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.
If the mercury level in a barometer suddenly decreases, it usually indicates a high-pressure system moving in, which is associated with improving weather conditions. This could mean clear skies and calm weather ahead.
The barometer shows low air pressure in a hurricane.My pain increases when the barometer drops below 29.8 to 30.A barometer gives a reading of air pressure.
the atmospheric pressure on top of a moutain would be lower than the atmospheric pressure down in a mine shaft
When the air pressure decreases, the level of mercury in the tube will rise. This is because the atmospheric pressure pushing down on the mercury in the dish will be less than the pressure from the column of mercury in the tube, causing the mercury to move up the tube until the pressures equalize.
!!! So, the air pressure between them will obviously be pushing down more on the barometer recording the higher air pressure, right? "So what!?" You say. So, this causes a few things. The air around the barometer with the high pressure may become very dense, while the air around the other barometer may be less dense. Hope I helped!!! :)
