A horizontal uniform glass tube of 100cm length sealed at both ends contains 10cm mercury column in the middle. The temperature and pressure of air on either side of mercury column are respectively0°C and 80cm of mercury. If the air column at one end is kept at 0°C and the other end at 273°C, the pressure of air which is 0°C is (in cm of Hg)
