If a barometer carries water instead of mercury, then the height of the column for a pressure equivalent to 75cm of mercury will be

Torricelli was the first do devise an experiment for measuring atmospheric pressure . He took calibrated hard glass tube , 1 m in lengt and of uniform cross section , closed at one end . He filled the whole tube with dry mercury taking care than no air or water droplets remain inside the tube , closed the opposite end of the tube tightly with thumb and inverted it . He put this inverted mercury tube into a mercury through , taking care that the end of the tube remains inside the mercury through , An interesting thing was noticed . Mercury in the tube fell down at first and then stopped at a particular position . The height was 76 cm above the free surface of mercury in the through . When the given tube was inclined or lowered in the mercury trough , the vertical haight of mercury level in the tube was always found constant . Torricelli explained this by saying that the free surface of mercury in the trough . Hence , the hydrostatic pressure exerted by the trough measures the atmospheric pressure . If this expriment uses water instead of mercury , then A. length of water will be equal to 76 cm B. length of water will be less than 76 cm C. length of water will be greater than 76 cm D. none of the above

A barometer is constructed with its tube having radius 1.0 mm. Assume that the surface of mercury in the tube is spherical in shape. If the atmospheric pressure is equal to 76 cm of mercury, what will be the height raised in the barometer tube? The contact angle of mercury with glass 135^@ and surface tension of mercury =0.466Nm^-1 . Density of mercury =13600kgm^-3 .

Express one atm pressure in terms of the height of mercury column.

If water be used to construct a barometer, what would be the height of water column at a standard atmospheric presure (76cm of mercury)?

The length of a faulty barometer is 90 cm and there is a little air above the mercury. When the atmospheric pressure is 76cm of Hg it reads 74.8 cm. What will be the true atmospheric pressure if the reading on the barometer is 74.3cm ?

A barometer reads 75cm if mercury. When 2.0cm^(3) of air at atmospheric pressure is introduced into space above the mercury level, the volume of this space cecones 50 cm^(3) . find the length by which the mercury column desecds.

A satellite revolves round the earth. Air pressure inside the satellite is maintained at 76 cm of mercury. What will be the height of mercury column in a barometer tube 1m long placed inn the satellite?

In a barometer, in place of mercury, if water is filled then what will its height?

In given figure, A uniform cylindrical tube closed at one end, contains a pallet of mercury 5cm long. When the tube is kept verticaly with the closed end downward, the length of the air column trapped is 30cm . Now the tube is inverted so that the closed end goes up find the new length of the air column trapped. atmospheric pressure =75cm of mercury. (Assume temperature remains constant in this process)
