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 mтАУ2
If mass of air at sea level is 1034 g cmтАУ2,calculate the pressure in Pascal.
Pressure is defined as force acting per unit area of thesurface.
= 1.01332 ├Ч 105┬аkg mтАУ1sтАУ2
We know,
1 N = 1 kg msтАУ2
Then,
1 Pa = 1 NmтАУ2┬а= 1 kg mтАУ2sтАУ2
1 Pa = 1 kg mтАУ1sтАУ2
┬аPressure= 1.01332 ├Ч 105┬аPa
