An alcohol barometer would have a higher column height when compared to a mercury barometer. If the Magdeburg hemispheres were 2 km above the sea, it would be simpler to separate them. Two pistons make up a hydraulic device, one with a tiny cross-section area and the other with a larger cross-section area.
Give An explanation of a mercury barometer
Barometric pressure, commonly known as air pressure or atmospheric pressure, is measured by a device called a mercury barometer using the various physical properties of mercury contained in a tube. Barometers are helpful instruments for weather forecasting since they can be used to predict impending changes in the weather. For instance, when the barometric pressure falls, it may indicate the impending arrival of storms, rain, or wind. On the other side, a rise in atmospheric pressure could suggest that dry, fair weather may start to develop soon. There is no assurance that the weather will behave as predicted, despite the fact that barometer reading interpretation is a fairly precise science.
