Estimate the total mass of the Earth's atmosphere, using the known value of atmospheric pressure at sea level.

Solution 74GP:

The amount of matter contained in the body which occupy space and has volume is known as the mass of the body. We have to estimate the mass of the earth with the help of atmospheric pressure.

Step 1 of 2</p>

Concept:

Pressure acting on the body is defined as the ratio of the force applied per unit cross sectional area. Mathematically,

…(1)

The pressure on a small area of Earth's crust is produced by the weight of air column above it.
