A long horizontal glass capillary tube open at both ends contains a mercury thread 1 m long at `0^@C`. Find the length of the mercury thread, as read on this scale, at `100^@C`.

A long horizontal glass capillary tube open at both ends contains a mercury thread 1m long at 0^0 C . A scale is etched on the glass tube. This scale is correct at 0^0 C . Find the length of mercury thread as shown by this scale at 100^0 C . Also find original length of thread at 0^0 C . ( gamma_mercury = 18.2 x 10^-5 K^-1, alpha_glass = 9 x 10^-6 K ^-1)

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 )
