Pressure is determined as force per unit area of the surface. The `SI` unit of pressure, pascal is as shown below:
`1 Pa=N m^(-2)`
If the mass of air at sea level is `1034 g cm^(-2)`, calculate the pressure in pascal.

Explanation

Pressure is the forece (i.e., weight) acting per unit area
But weight = mg
`therefore" Pressure"="Weight per unit area"=(1034gxx9.8ms^(-2))/(cm^(2))`
`=(1034gxx9.8ms^(-2))/(cm^(2))xx(1kg)/(1000g)xx(100cm)/(1m)xx(100cm)/(1m)xx(1N)/("kg ms"^(-2))xx(1Pa)/("1 N m"^(-2))`
`=1.01332xx10^(5)Pa`
