10. uses of mercury barometer. A mercury barometer is a device that uses the physical properties of mercury in a tube to measure barometric pressure. Mercury Barometers are used for:-. 1. Measurement of atmospheric pressure. 2. Determining the altitude of a place. 3.
In it, barometer works by balancing the mercury in the glass tube against the outside pressure. Q.2: What are some applications of Barometer? Solution: A mercury barometer is a device that uses the physical properties of mercury in a tube to measure barometric pressure. Mercury Barometers are in use for:-Measurement of atmospheric pressure
Aneroid Barometer Mechanism. A metal cell which contains a small amount of air or a series of these cells combined together operate the aneroid barometer. When the air pressure increases, the sides of these cells come together quickly. The base of the instrument secures one side. After that, the other side joins the structure of pulleys and ...
In a simple barometer, some air is trapped in the space above the mercury column. Let H be the height of the mercury column initially. When the tube is further pushed into the vessel, what happens to the height of the mercury column ‘H’ in the tube?
A barometer tube, containing mercury, is lowered in a vessel containing mercury until only 50 c m of the tube is above the level of mercury in the vessel. If the atmospheric pressure is 75 c m of mercury, what is the pressure at the top of the tube
The atmospheric pressure and height of barometer column is 10 5 P a and 760mm respectively on the earth surface. If the barometer is taken to moon then column height will be
The height of a mercury column in a barometer in a Calcutta library was recorded to be 75cm.Calculate this pressure in SI and CGS units using the following data : Specific gravity of mercury = 13.6,Density of water = 10 3 kg/m 3,g = 9.8 m/s 2 at Calcutta .Pressure = hpg in usual symbols.
The height of mercury in the barometer tube is 70 cm due to entrapped air in it as shown in figure. Now from this position tube is pulled up slightly, then length of the mercury column in the tube will. Remain 70 cm; Slightly more than 70 cm; Slightly less than 70 cm; Can't say
a barometer is constructed with its tube having radius 1.0mm.assume that the surface of mercury in the tube is spherical in shape.if the atmospheric pressure is equal to 76cm of mercury,what will be the height raised in the barometer tube?the contact angle of mercury with glass =135degree and surface tension of mercury=0.465N/m.density of mercury=13600kg/m^3.
The height of mercury in the barometer tube is 70 cm due to entrapped air in it as shown in figure. Now from this position tube is pulled up slightly, then length of the mercury column in the tube will A not perfect vacuum III se answer: Remain 70 cm Slightly more than 70 cm Slightly less than 70 cm Can't say
