2. Identify the Space Above Mercury: In a simple barometer, when the mercury is inverted, there is a space above the mercury column in the tube. This space is crucial for understanding how the barometer works. 3
This picture is out of date: I've since added more mercury that came from a leaking barometer I got at a school auction, and cleaned it all up by using a coffee filter with a pinhole in the bottom of it (a technique I learned fromTimothy Brumleve). Amazingly, you can simply let dir...
If a certain pressure supports a 256 mm high column of mercury, how high a column of water would it support? The densities of mercury and corn oil are 13.5 g/ML and 0.92 g/mL, respectively. If corn oil were used in a barometer, what would be the height of the column, in meters,...
You see, if the height of the mercury [barometer] column is less on the top of a mountain than at the foot of it (as I have many reasons for believing, although everyone who has so far written about it is of the contrary opinion), it follows that the weight of the air must be t...
How does mercury create a vacuum in a barometer? WHAT TYPE OF REACTION CAUSES THE FORMATION OF METALLIC MERCURY AND NAME THE REAGENT RESPONSIBLE? WHAT CAUSES THE SILVER CHLORIDE TO DISSOLVE AND NAME THE REAGENT? WHAT EVENTUALLY CAUSES THE SILVER CHL ...
How much does 1.0 ft^3 of mercury weigh given the density of mercury is 13.6 g/ml? What is the pressure (in mm Hg) exerted by a mass of 937 g applied to a cross-sectional area of 15.2 mm^{2}? If you wan...
