This problem is providing the atmospheric pressure at 2000 m altitude which is 560. mmHg and asks for this pressure in units of atmospheres, which after doing the calculations, the result is 0.737atm.
<h3>Atmospheric pressure:</h3><h3 />
In this case, we can firstly define the concept of atmospheric pressure, also known as barometric pressure, as that pressure exerted by a column of air over a specific point in space at a defined altitude.
<h3>Units conversion in pressure:</h3><h3 />
In order to get the correct conversion, we use the following equivalence statement relating mercury millimeters and atmospheres:
760 mmHg = 1 atm
Hence, the required conversion turns out to be:
