A barometer reads a pressure of 135000 Pa. What is the pressure in atm? 1330 atm...
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
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.

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?

One of the largest barometers ever built was an oil-filled
barometer constructed in Leicester, England in 1991. The oil had a
height of 12.2 m. Assuming a pressure of 1.013 × 105 Pa,
what was the density of the oil used in the barometer? uming a pressure of 1.013 ×
105 Pa, what was the density of the oil used in the barometer?

The density of mercury is 13.5 g/mL and the density of water is 1.00 g/mL. If a mercury barometer reads 751 mmHg, what is the barometric pressure in centimeters of water (cmH,O)? barometric pressure: cmH20
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...
