13. A mercury barometer, with a tube of uniform diameter and length 840mm above the mercury level in the reservoir, reads 740mm on a day when the atmospheric pressure is 760mm of mercury. Estimate the pressure of the atmosphere on a day when it reads 720mm. Assume the average temperature is the same on both days. (a) 736.60 mmHg (b) 736.75 mmHg (c) 736.70 mmHg (d) 730.70 mmHg

Step 1
We need to estimate the atmospheric pressure on a day when the barometer reads 720 mm, given that on a day when the barometer reads 740 mm, the atmospheric pressure is 760 mmHg. Show more…

On a day, a laboratory barometer indicates that the atmospheric pressure is 764.7 torr. A sample of gas is placed in a flask attached to an open end mercury manometer and a meter stick is used to measure the height of the mercury in the two arms of the U tube. The height of mercury in the open ended arm is 140.7 mm, and the height in the arm in contact with the gas is 103.8 mm. What is the pressure of the gas in the flask (a) in atmospheres? (b) in kilopascals .

In a Torricelli barometer, a pressure of one atmosphere supports a 760 mm column of mercury. If the original tube containing the mercury is replaced with a tube having twice the diameter of the original, the height of the mercury column at one atmosphere pressure is ______ mm Hg. If 3.21 mol of a gas occupies 56.2 L at 44°C and 793 torr, what volume does 5.29 mol of this gas occupy under the same conditions? Which statement about atmospheric pressure is false?
