1. A student reads a barometer in the laboratory and finds the prevailing atmospheric pressure to be 699 mm Hg. Express this pressure in atmospheres, kilopascals, torrs, pounds per square inch, and pascals. Hint: 1 atm = 101.3 kPa = 760 torr = 760 mm Hg = 14.69 psi = 1.013×105 Pa mm Hg atm kPa torr psi Pa 699 2. An automobile tire is inflated to a pressure of 29.2 psi. Express this pressure in atmospheres, kilopascals, inches Hg,...
1. A manometer is attached to a sample of gas that occupies a volume of 2.5 liters. The mercury level in the arm of the manometer attached to the gas sample is 19.5 torr higher than that of the arm open to the atmosphere. Atmospheric pressure is measured to be 0.98 atm. What is the pressure of the sample of gas? (6 pts) 2. A balloon has a volume of 2.32 liters at 24.0°C. The balloon is heated to 48.0°C....
At an atmospheric pressure of 745 mm Hg, what is the pressure of He gas inside a cylinder that is attached to an open-end manometer in which the level of mercury in the open side of the manometer is 25 mm Hg higher than the side that is attached to the gas cylinder?
A barometer can measure atmospheric pressure using the variation of pressure with depth of a fluid. Vacuum (P 0) A glass tube is filled with mercury (p 13,600 kg/m3) and placed upside-down in a bowl that also contains mercury. O Determine the height h. Enter the value in mm but do not include the unit in your response. Pat O 1 atmosphere 1.01x105 Pa
A student reads a barometer in the laboratory and finds the prevailing atmospheric pressure to be 678 mm Hg. Express this pressure in atmospheres, kilopascals, torrs, pounds per square inch, and pascals. Hint: 1 atm = 101.3 kPa = 760 torr = 760 mm Hg = 14.69 psi = 1.013×105 Pa mm Hg atm kPa torr psi Pa 678
Air pressure is measured by a barometer. One type of barometer utilizes an evacuated, calibrated tube inverted in a pool of mercury that is open to the atmosphere. As air pressure increases, the mercury will rise in the column until the weight of the mercury in the column equals the force exerted by the air on the surface of the pool. The barometer shown here (Figure 1) measures atmospheric pressure in millimeters of mercury (mmHg ). According to this barometer,...
The following data was obtained: atmospheric pressure: 752 torr water vapor pressure: 22 torr height of water column: 158 mm Calculate the partial pressure of the dry gas. Density of mercury if 13.6 g/cm3 and assume the desnity of the solution is 1.00 g/cm3/
A ballerina weighs 103 lbs and is up on her toes with only 10.0 cm^2 of her slippers in contact with the floor. What pressure is she exerting on the floor? Mineral oil can be used in place of mercury in manometers when small pressure changes are to be measured. What is the pressure of an oxygen sample in mm of mineral oil if its pressure is 28.5 mm Hg? (d of mineral oil = 0.88 g/mL; d of Hg...
If the gas inside the flask is cooled so that its pressure is reduced from 797.3 torr to a value of 715.7 torr what will be the height of the mercury in the open arm? 49.0 mm 95.6 mm 144.6 mm 120.1 mm
Please answer the red sentences is the hint An engineer is installing an open-end mercury manometer attached to a pipe that will eventually carry pressurized gas. While the pipe is open to the atmosphere, she adds enough mercury into the manometer that the mercury level in both arms of the manometer is 790.0 mm above the bottom of the Pipe open to manometer. (See Fig. 1) If the end of the open arm of the manometer is 1015.0 mm above...
