What is a barrometer?
An apparatus used to measure atmospheric pressure and its weather related changes.
What is the name for pressure caused by the weight of the atmosphere?
Simply put, atmospheric pressure is the force exerted on a measuring point by the weight of the air molecules on top of that point. Standard atmospheric pressure, measured at sea level at 59F or 15C, is used as a reference point and is equal to 29.92 inches of mercury or 1013 millibars of pressure.
Why mercury is used in sphygmomanometer?
To make the measuring apparatus a managable size i.e approx 10 inches high for Mercury tube. If water was used the tube would need to be much larger and the apparatus would be unmanageable when being carried around.
What tool is used for measuring air pressure?
