Text Solution

AI Generated Solution

To express one atmosphere of pressure in terms of the height of a mercury column, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Concept of Atmospheric Pressure**: Atmospheric pressure is the pressure exerted by the weight of air in the atmosphere. It is commonly measured using a barometer. 2. **Use of Barometer**: A barometer is a device that measures atmospheric pressure using a column of mercury. In a typical barometer setup, a glass tube is filled with mercury and inverted into a container of mercury. ...

Two vessel connected by a pipe with a sliding plug contain mercury. In one vessel, the height of murcury column is 39.2 cm and its temperature is 0^@ C , while in the other, the height of mercury column is 40 cm and its temperature is 100^@ C . Find the coefficient if cubical expansion for mercury. The volume of the connecting pipe should be neglected.

A horizontal uniform glass tube of 100cm length is sealed at both ends contains 10 cm mercury column in the middle , the temperature and pressure of air on either side of mercury column are repectively 31^(@)C and 76cm of mercury, if the air column at one end is kept at 0^(@)C and the other end at 273^(@)C then pressure if air which is 0^(@)C is (in cm of Hg )

A container of cross-section area 'S' and height 'h' is filled with mercury up to the brim. Then the container is sealed airtight and a hole of small cross section area 'S//n' (where 'n' is a positive constant) is puched in its bottom. Find out the time interval upto which the mercury will come out from the bottom hole. [Take the atmospheric pressure to be equal to h_(0) height of mercury column: h gt h_(0) ]

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?

The correct expression of partial pressure in terms of mole fraction is

A barometer correctly reads the atmospheric pressure as 76cm of mercury. Water droplets are slowly introduced into the barometer tube by a dropper. The height of the mercury column first decreases and then become constant. If the saturation vapour pressure at the atmospheric temperature is 0.80cm of mercury, find the height if the mercury column when it reaches its minimum value.

A column of mercury is in the middle of horizontal tube of uniform cross section closed at both ends. The pressure of the enclosed air column on either side of the mercury is 75 cm of mercury column. When the tuve is placed vertical the length air below the mercury column is (3)/(5) th of that above it. if length of mercury column is 10n cm. find n.

The liquids shown in figure in the two arms are mercury (specific gravity =13.6) and water. If the difference of heights of the mercury columns is 2 cm, find the height of the water column. ,
