The diagram below shows a manometer containing mercury that is sealed at one end. What happens to the
distance h when the manometer is taken to the top of a mountain?
vacuum
h
O A. It decreases, because atmospheric pressure increases with height.
O B. It increases, because atmospheric pressure increases with height.
O C. It decreases, because atmospheric pressure decreases with height.
OD. It increases, because atmospheric pressure decreases with height.
Answers
Answer:
c.it decrease, because
Answer:
The correct answer is
option [C].
IT DECREASES, BECAUSE ATMOSPHERIC PRESSURE DECREASES WITH HEIGHT.
Because of the relationship between height and air pressure, it falls.
Explanation:
An instrument for determining the pressure acting on a fluid column that consists of a U-shaped fluid tube in which the liquid rises to various heights in the two arms due to different exerts pressure in the two arms of the tubes.
We utilize a manometer as a tool to gauge the pipelines' pressure. Additionally, it is frequently referred to as a liquid-filled U-shaped tube.
One of the most precise instruments for measuring temperature in the lower elevations is a manometer. Measurement of pipe working fluid, HVAC system pressure, and air pressure are examples of typical manometer applications. Liquids used in manometers often include mercury, liquid, and light oils.
Altitude rises result in a drop in atmospheric pressure.
As we are aware, the density of the air increases at the surface of the planet (due to gravity) and starts to decrease as we ascend, finally leading to blank space, i.e. beyond the earth's atmosphere.
As a result of the larger density, the atmosphere pressure is elevated at lower altitudes. At higher elevations, the density is lesser and the atmospheric pressure is low.
