Step-by-Step Solution:1. Definition of Atmospheric Pressure: Atmospheric pressure is defined as the pressure exerted by the weight of the air in the atmosphere on a surface. This pressure is due to the vari
Atmospheric pressure is caused by the weight of air molecules above the atmosphere. The layer of air exerts a force on the surface of the earth. The force per unit area, by the atmosphere, on the surface of any object on the earth is called atmospheric pressure. At the sea level this ...
Atmospheric pressure is often measured with a mercury barometer; however, since mercury is not a substance that humans commonly come in contact with, water often provides a more intuitive way to visualize the pressure of one atmosphere. One atmosphere is the amount of pressure that can lift water...
