A liquid has density = 1.20g/ml. Which barometer will be taller, one using the liquid or one using water?
A.the liquid
B.water
C.both the same height
So option B is correct as height of water is greater than height of given liquid present in barometer

The drawing shows a mercury barometer. Consider two barometers, one using mercury and another using an unknown liquid. Suppose that the pressure above the liquid in each tube is negligible. The height of the unknown liquid is 18.8 times greater than the height of the mercury. Find the density of the unknown liquid. The drawing shows a mercury barometer. Consider two barometers, one using mercury and another using an unknown liquid. Suppose that the pressure above the liquid in each...
1. A volatile organic liquid with known molecular weight is added to a vapor density flask which has a known volume. The flask is heated using a boiling water bath until all of the liquid has evaporated. After heating for an additional 1 or 2 minutes, the flask is removed from the boiling water bath, corked, and cooled using a room temperature water bath. Predict the mass of condensed vapor. Temperature of the hot water bath (ºC): 99.5 Volume of...

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
Which of the following concerning a barometer or manometer is/are true? Pressure is directly proportional to the height of the liquid used in the device. Pressure is directly proportional to the density of the liquid used in the device. Pressure is independent of the acceleration of gravity.
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,...

A.1 only B.2 only C.3 only D.1 and 2 E.1, 2, and 3 Which statement is inconsistent with the kinetic theory of an ideal gas? A.Most of the volume occupied by a gas...
In principle many different liquids could be used in a barometer. Mercury is usually preferred by virtue of its low vapour pressure and high density. As part of a school project, you have decided to build a barometer using water. Assuming the maximum pressure that the instrument will need to read is 1.05 atm, determine the height of the column required if (a) you ignore the vapour pressure of water or (b) you take the vapour pressure of water (PH2O=3.17...
18. An unknown liquid has a density of 1.32 g/mL. What is the volume of a 14.7-8 sample of the liquid? a. 11 ml b. 11.1 mL c. 11.13 mL d. 11.14 mL e. 11.136 ml
Liquid nitrogen has a density of 0.808 g/mL and boils at 77 K. Researchers often purchase liquid nitrogen in insulated 185 L tanks. The liquid vaporizes quickly to gaseous nitrogen (which has a density of 1.15 g/mL at room temperature and atmospheric pressure) when the liquid is removed from the tank. Suppose that all 185 L of liquid nitrogen in a tank accidentally vaporized in a lab that measured 10.00 m times 10.00 m times 3.50 m. Part A What...
