Question

What is the magnitude of air pressure in pascals in the SI system?

Answer 1

1. Pressure acting on a body per unit area due to the air above it is called air pressure.
2. Since air has mass, it exerts pressure on the body below it.
3. SI unit of pressure is Pascal.
4. The magnitude of the average air pressure on the surface of the earth in the SI unit system is $1.013\times {10}^{5^{}}Pa$.
