The air pressure inside a submarine is 0.62 atm. What would be the height of a

column of mercury balanced by this pressure?

471.2 mmHg

Explanation:

Given that:

The air pressure inside a submarine is 0.62 atm

What would be the height of a column of mercury balanced by this pressure?

The standard air pressure in a mercury containing vessel keeps the mercury raised up to 760 mm higher, this is relatively synonymous to the force from the weight of that column in the vessel.

Now in 0.62 atm air pressure inside a submarine, the height of the column of mercury balanced by this pressure will be:

0.62 * 760 mmHg = 471.2 mmHg
