the height of mercury in a fauilty barometer is 75 cm and the tube above mercury is 10 cm long. The correct barometer reading is 76 cm. when the faulty barometer reads 74 cm, find the true barometer reading .

At the top of a mountain, a thermometer reads 7^(@)C and a barometer reads 70 cm of Hg. At the bottom of the mountain, they read 27^(@)C and 76 cm of Hg respectively. Compare the density of air at the top with that at the bottom of the mountain.

A faulty barometer tube is 90 cm long and it contains some air above mercury. The reading is 74.5 cm when the true atmospheric pressure is 76 cm. What will be the true atmospheric pressure if the reading on this barometer is 74 cm? (H = 10m of water column)
