Air is trapped in the space (labeled) above the mercury level in the tube of a barometer, which measure 745 mm Hg. If the atmospheric pressure is 760 mm Hg, then the pressure of the trapped air is

Determine the atmospheric pressure at a location where the barometric reading is 735 mmHg. Take the density of mercury to be 13,600 kg/m3. Express your answer in kPa.

) What atmospheric pressure is?

A mercury manometer measures a pressure of 200 mmHg. What is this pressure in atm?

Atmospheric pressure, as a function of altitude. (1 Point)

A scientist uses a mercury barometer to measure the atmospheric pressure at the top of a mountain. He finds that the height of mercury in the column is lower than it is at sea level. Which of the following best explains this finding?A.The atmosphere exerts more force on the mercury at the top of the mountain than at sea level.B.Due to the height, the force of gravity is stronger at the top of the mountain than at sea level.C.Mercury behaves as a more dense substance at the top of the mountain than it does at sea level.D.The atmosphere weighs less at the top of the mountain than it does at sea level.
