The Total solution for NCERT class 6-12
Pressure is determined as force per unit area of thesurface. The SI unit of pressure, Pascal is as shown below:
1Pa = 1N m–2
If mass of air at sea level is 1034 g cm–2,calculate the pressure in Pascal.
Pressure is defined as force acting per unit area of thesurface.
= 1.01332 × 105 kg m–1s–2
We know,
1 N = 1 kg ms–2
Then,
1 Pa = 1 Nm–2 = 1 kg m–2s–2
1 Pa = 1 kg m–1s–2
Pressure= 1.01332 × 105 Pa
