The temperature and pressure at Simla are `15.0^(@)C` and 72.0cm of mercury and at Kalka these are `35.0^(@)C` and 76.0 cm of mercury. Find the ratio of air density at Kalka to the air density at Simla.

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 faulty barometer contains certains amount of air and saturated water vapour . It reads 74.0cm when the atmospheric pressure is 76.0cm of mercury and reads 72.10cm when the atmospheric pressure is 74.0cm of mercury.Saturation vapour pressure at air temperature =1.0cm of mercury. Find the length of the baromerer tube above the mercury level in the reservoir.
