What is the pressure of the gas in this mercury manometer if h = 53 mm and atmospheric pressure is 759 mmhg?

Given:

Atmospheric pressure = 759 mmHg

Height of manometer, h = 53 mm

To determine:

The gas pressure

Explanation:

The pressure of the gas can be calculated as follows-

P(gas) = P(atm ) + h

where: P(atm) is the atmospheric pressure

            h = column height

P(gas) = 759 + 53 = 812 mmHg

Ans: The pressure of gas in the mercury manometer is 812 mmHg

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
