How many CM does a mercury rise in a barometer at sea level?

A mercury barometer. A pressure of 1 atm will support a column of mercury 76 cm high. That is, a pressure of 1 atm will support a column of mercury 76.0 cm high. Deviations of the height of the column from the normal value of 76.0 cm reflect changes in the atmospheric pressure due to local weather conditions.

What is the barometric height of mercury?

The height of mercury barometer is 76 cm and density of mercury is 13.6 gcc .

What is the height of mercury column in barometer?

At sea level and at a temperature of 0° Celsius (C), the height of the mercury column is approximately 30 inches, or 76 centimeters. This represents a pressure of approximately 14.7 psia. The 30-inch column is used as a reference standard.

Why does mercury rise in a barometer?

The greater the air pressure, the higher the mercury rises. We use mercury in barometers because it’s more convenient than using water. Water is less dense (less heavy, in effect) than mercury so air pressure will lift a certain volume of water much higher up a tube than the same volume of mercury.

What is most likely to be the level of mercury in the barometer if it is taken to a higher altitude would it be 76 mm 76 cm 78 cm 0r 74 cm explain your answer?

At higher altitudes, the atmospheric pressure is decreased and so the column of mercury will not rise as high.

How is barometric height altered when a drop of water is introduced in a mercury barometer?

the barometer height will decrease if a drop of water is introduced in a mercury barometer, which is due to the pressure exerted by water vapour.

What is the dimension of mercury?

Mercury’s diameter is 3,030 miles (4,878 km), comparable to the size of the continental United States. This makes it about two-fifths the size of Earth. It is smaller than Jupiter’s moon Ganymede and Saturn’s moon Titan.

What length of water column is equivalent to 0.75 m of mercury column?

10.34 m of water column is equivalent to 0.76 m of Mercury column.
