Mercury is employed in the barometer because its density is sufficiently high for a relative short column to be obtained. Explain why water cannot be used in place of mercury in a barometer.

How It Works Barometers Weather Instruments Barometer

Because of this property when there is a change in pressure the change in height of the mercury in the barometer tube will be very reasonable.

. Mercury has high density. Why is mercury used as a barometric fluid. Why Mercury is Used in Barometers.

Mercury has high density. Its relative density is 13534 times that of water. Why mercury is used in barometer instead of water.

The use of mercury in barometers is a practice that dates back to the 17th century. Explain why water cannot be used in place of mercury in a barometer. H water P atm ρ water.

Mercury has many advantages when used as a measuring liquid in a barometer tube. In the barometer mercury is used as the barometric liquid. Why is mercury used as.

Mercury is commonly used in barometers because its high density means the height of the column can be a reasonable size to measure atmospheric. Why dont we use water instead of mercury in barometer. How does mercury barometer and aneroid barometer.

Mercury is employed in the barometer because its density is sufficiently high for a relative short column to be obtained. So to measure the atmospheric pressure which is 760 mm of mercury you need a barometer with. There are two forms of mercury barometer stick you read the mercury height by looking directly at the top of the column inside the glass tube and compare it to a scale of.

Mercury is used in barometers and not water. Why mercury is used in pressure barometer. By the use of mercury in a barometer the total height of the barometer gets reduced as it has a higher density.

Mercury is employed in the barometer because its density is sufficiently high for a relative short column to be obtained. The aneroid barometer is more durable and compact and much easier to read. By comparison water has a.

Mercury is used in barometers because of its high density. Answer 1 of 33. This is because the high density of mercury gives a reasonable.

Why mercury is used in pressure barometer. P atm ρ water g h water. Why cant we use water instead of mercury in barometer.

Thus from the formula of liquid pressure we can write. Why is mercury preferred over water in a barometer. As well as the mercury has lower vapour pressure thus its molecules never get.

A Torricellian barometer sometimes called a mercury barometer is an inverted upside-down glass tube standing in a. Mercury has several advantages over water which was why it was preferably used to make the very first barometers a long time ago. At 139 gcm2 mercury is the most dense substance to exist as a liquid at room temperature.

In the barometer mercury is used as the barometric liquidMercury has high density. The Science Behind It. The atmospheric pressure at sea level.

1Mercury is more dense. Why Do Barometers Use Mercury. Why Is Mercury Used In A Barometer.

Why Is Pressure Measured In Mercury. These advantages would be-. We know that the value of normal atmospheric pressure is 101 325 Pa.

Why mercury is used in pressure barometer. Mercury is employed in the barometer because its density is sufficiently high for a relative short column to be obtained. Mercury is commonly used in barometers because its high density means the height of the column can be a reasonable size to measure.

Because of this property when. What is the principle of an aneroid barometer state its advantages over a mercury barometer. The atmospheric pressure at sea level 76cm of Hg.
