3. An open glass tube is immersed in mercury so that a length of 8 cm of the tube projects above the mercury. The tube is then closed and raised through 44 cm. What length of the tube will be occupied by the air after it has been raised ? Given 1 atm = 76 cm of Hg. (Ans. 15.4 cm) is lowered

An open glass tube is immersed in mercury in such a way that a length of 8 cm extends above the mercury level. The open end of the tube is then closed and sealed and the tube is raised vertically up by additonal 46 cm. What will be length of the air column above mercury in the tube now? (Atmospheric pressure = 76 cm of Hg

An open glass tube is immersed in mercury in such a way that a length of 8 cm extends above the mercury level. The open end of the tube is then closed and sealed and the tube is raised vertically up by additional 46 cm. What will be length of the air column above mercury in the tube now? (atmospheric pressure =76 cm of Hg)
