Question

what is the mass of vertical column of air that exerts pressure of 1 atm over a10m by 10m square surface

Answer 1

`m=1.01* 10^6\ kg`

Step-by-step explanation:

Given that,

Pressure, P = 1 atm = 101325 Pa

Area of the square surface, A = 10² = 100 m²

We need to find the mass of vertical column of air. We know that, pressure is equal to the force acting per unit area. So,

`P=(mg)/(A)\\\\m=(PA)/(g)\\\\m=(101325* 10^2)/(10)\\\\m=1.01* 10^6\ kg`

So, the required mass of the vertical column of air is
`1.01* 10^6\ kg`.
