The weight of air in a column 1-m2 in cross section that extends from sea level to the top of the atmosphere is?

Sagot :

From sea level to the top of the atmosphere, a column of air with a 1-m2 cross section weighs 101,000 N.

To find the answer we have to know about the pressure.

What is Pressure?

  • The pressure at a point on a surface is the thrust acting per unit area around that point.

                    [tex]Pressure, P=\frac{Thrust}{Area}=\frac{F}{A}[/tex]

  • A particular mass of air is contained in a column that rises from the ocean to the top of the atmosphere. Then,

                   [tex]P=P_a=1.013*10^5 pascal[/tex]

Pa is the atmospheric pressure at the sea level.

  • By combining both the equations, we get the weight of air,

                                       [tex]\frac{F}{A}=P_a[/tex]

              [tex]F=W=P_a*A=1.013*10^5*1=101300N[/tex]

Thus, we can conclude that, the weight of air in a column 1-m2 in cross section that extends from sea level to the top of the atmosphere is 101300N.
