atmospheric pressure is 25.65 inches of mercury. Convert inches of mercury to Torr. ( there are 2.54cm to the inch )
The pressure unit torr is defined as the pressure that will
support a column of mercury 1 mm high. Meteorologists often give
barometric pressure in inches of mercury, defined analogously. The
density of mercury is.
Part A
Express torr in SI units.
1 torr = Pa
Part B
Express inch of mercury in SI units.
1 inch of mercury = kPa
Question 1 (1 point) The atmospheric pressure was measured to be 29.97 inches of mercury (inHg). Given the fact that 1 atm = 29.92 inHg, convert the measured atmospheric pressure into atm. Use four significant figures in your answer. Your Answer: Answer units
What is standard atmospheric pressure (760 mmHg) in inches mercury (in Hg)? (2.54 cm = 1 in)
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/
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,...
Suppose atmospheric pressure is 29.74 inches. Convert this to atm. When the ideal gas law iconstant 0.0821 atm L/ K mol is used, the pressure must be in atm.
Part A The barometer shown here (Figure 1) measures atmospheric pressure in millimeters of mercury (mmHg). According to this barometer, what is the atmospheric pressure P in inches of mercury (inHg)? Express your answer in inches of mercury using five significant figures. P = inHg SubmitHintsMy AnswersGive UpReview Part Part B At a pressure of 897 mbar , what would the height of the mercury in the column of a mercury barometer? Express your answer numerically in millimeters of mercury....
a faulty barometer reads 72.6cm mercury when the atmospheric pressure is 75.0cm mercury. calculate the atmospheric pressure when this barometer reads 72.0cm mercury
2. A barometer reads the atmospheric pressure 764.7 torr. A sample of gas is placed attached to an open-end mercury monometer. The level of mercury in the op arm of the monometer has a height of 136.4 mm, and that in the arm that is in cont with the gas has a height 103.8 mm. What is the pressure of gas in atmosphere?
The column of a mercury barometer is calibrated in linear units
(such as inches or millimeters) and thus the air pressure observed
on such a barometer is reported in terms of these linear units.
This measurement of pressure can be converted to other common
pressure units. Some conversion factors are shown here.
1mm Hg = 1torr
1 atm = 760mm Hg
1 atm = 1.01325 bar
1 Pa = 10-5 bar
1 in = 2.54 cm
1 cm = 10...
